PANoptosis is a newly defined type of programmed cell death (PCD), which is triggered by a variety of stimuli and covers three known forms of PCD: apoptosis, pyroptosis and necroptosis. In physiological state, cell death plays an important protective role against pathogen invasion, but its over-activation may aggravate inflammatory response and cause tissue damage. Studies have shown that the occurrence and progression of acute lung injury/acute respiratory distress syndrome (ALI/ARDS), asthma, chronic obstructive pulmonary disease (COPD) and other lung diseases are closely related to PANoptosis. The purpose of this review is to deeply explore the molecular mechanism of PANoptosis and its regulatory factors in lung diseases, in order to discover potential therapeutic targets and provide new targets and innovative ideas for clinical treatment for lung diseases.

OBJECTIVE: Patients with severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection frequently develop central nervous system damage, yet the mechanisms driving this pathology remain unclear. This study investigated the primary pathways and key factors underlying brain tissue damage induced by the SARS-CoV-2 beta variant (lineage B.1.351). METHODS: K18-hACE2 and C57BL/6 mice were intranasally infected with the SARS-CoV-2 beta variant. Viral replication, pathological phenotypes, and brain transcriptomes were analyzed. Gene Ontology (GO) analysis was performed to identify altered pathways. Expression changes of host genes were verified using reverse transcription-quantitative polymerase chain reaction and Western blot. RESULTS: Pathological alterations were observed in the lungs of both mouse strains. However, only K18-hACE2 mice exhibited elevated viral RNA loads and infectious titers in the brain at 3 days post-infection, accompanied by neuropathological injury and weight loss. GO analysis of infected K18-hACE2 brain tissue revealed significant dysregulation of genes associated with innate immunity and antiviral defense responses, including type I interferons, pro-inflammatory cytokines, Toll-like receptor signaling components, and interferon-stimulated genes. Neuroinflammation was evident, alongside activation of apoptotic and pyroptotic pathways. Furthermore, altered neural cell marker expression suggested viral-induced neuroglial activation, resulting in caspase 4 and lipocalin 2 release and disruption of neuronal molecular networks. CONCLUSION These findings elucidate mechanisms of neuropathogenicity associated with the SARS-CoV-2 beta variant and highlight therapeutic targets to mitigate COVID-19-related neurological dysfunction.

Objective To explore the regulatory effects of cytokines interleukin(IL)-1β,IL-6,tumor necrosis factor alpha(TNF-ɑ),gamma interferon(IFN-γ),granulocyte colony-stimulating factor(G-CSF),and granulocyte-macrophage colony-stimulating factor(GM-CSF)on spontaneous pyroptosis in neutrophils.Methods Neutrophils isolated from mouse bone marrow by density-gradient centrifugation were cultured in vitro for 20 h with or without 10,50 or 100 ng/mL IL-1β,IL-6,IFN-γ,G-CSF or GM-CSF,or for 12 h with or without 1,10 or 50 ng/mL TNF-α.After incubation,cells were stained with annexin Ⅴ(AV)/propidium iodide(PI),and the proportions and absolute number of neutrophils undergoing different forms of cell death were determined by fluorescence microscopy combined with manual counting.Pyroptotic neutrophils were identified by cell morphology in conjunction with AV/PI staining.Flow cytometry with counting beads was employed to measure the proportions and number of AV/PI-stained Ly6g⁺neutrophils in different forms of cell death.Western blotting was employed to assess the cleavage and activation levels of cysteinyl aspartate-specific proteinase-3(caspase-3)and gasdermin E(GSDME).Results Treatment with IL-1β or IL-6 had no significant effect on the proportion or number of neutrophils undergoing spontaneous pyroptosis.After 12 h of treatment with TNF-α at 1,10,and 50 ng/mL,the proportions of pyroptotic neutrophils were(14.79±0.45)%,(19.99±3.02)%,and(20.66±1.99)%,respectively,higher than that[(10.22±1.12)%]in the untreated control(P=0.024,P<0.001,and P<0.001,respectively).Treatment with 10,50,and 100 ng/mL IFN-γ for 20 h reduced the proportion of pyroptotic neutrophils from(17.43±1.88)%to 12.00%(all P<0.001).G-CSF at 10,50,and 100 ng/mL reduced the proportion of pyroptotic cells to around 6.00%and greatly inhibited the cleavage of both caspase-3 and GSDME.After 20 h of treatment with 10,50,and 100 ng/mL GM-CSF,the proportions of pyroptotic neutrophils decreased to(7.52±0.53)%,(5.27±2.30)%,and(0.64±1.11)%,respectively.Conclusions Neither IL-1β nor IL-6 affects GSDME-mediated spontaneous pyroptosis in neutrophils.TNF-ɑ induces spontaneous pyroptosis in neutrophils,whereas IFN-γ,G-CSF,and GM-CSF demonstrate inhibitory effects.

Objectives miR-207 has been identified as being expressed in natural killer (NK) cell exosomes that play a role in disease progression; however, to date, there are no studies specifically linking miR-207 to tuberculosis (TB). Methods Bioinformatics methods employed for prediction, followed by a dual luciferase reporter assay to determine whether lysosome-associated membrane protein 2 (LAMP2) is targeted by miR-207. The experiments were divided into four groups using the liposome transfection method (OP-LAMP2 group: co-transfected with miR-207 mimics and LAMP2 overexpression plasmid; EP group: co-transfected with mimics NC and null-loaded plasmid; siLAMP2 group: transfected with siLAMP2; and siLAMP2-NC group: transfected with siLAMP2-NC). TB infection was modeled using H37Ra-infected Ana-1 cells. The impact of LAMP2 on intracellular mycobacterial load and clearance of extracellular residual mycobacteria were assessed by tuberculosis colony-forming unit counting. Flow cytometry was used to assess the total apoptosis rate. Real-time fluorescent quantitative PCR was conducted to determine the relative expression of LAMP2, apoptosis genes, pyroptosis genes, and autophagy genes. Western blot analysis was performed to measure the relative expression of LAMP2 proteins, apoptosis proteins, pyroptosis proteins, and autophagy proteins. Results Dual luciferase reporter assay test showed that there was a targeting relationship between LAMP2 and miR-207. The transfection model was successfully constructed under real-time fluorescent quantitative PCR and Western blot statistical analysis, and microscopic observation. The infection model was successfully established under microscopic observation. Colony forming unit counting revealed that the number of colonies in the OP-LAMP2 group was lower than that in the EP group, while the number of colonies in the siLAMP2 group was higher than that in the siLAMP2-NC group. Flow cytometry assay revealed that the total apoptosis in OP-LAMP2 group was lower than that in EP group, and the total apoptosis in siLAMP2 group was higher than that in siLAMP2-NC group. Real-time fluorescence quantitative PCR and Western blot analysis revealed that the relative expression of apoptosis and pyroptosis-related proteins and genes in the control group was lower in the OP-LAMP2 group compared to the EP group, and higher in the siLAMP2 group compared to the siLAMP2-NC group. Real-time fluorescence quantitative PCR detected that the relative expression of autophagy positively regulated genes Microtubule-associated protein 1 light chain 3(LC3)and Beclin1 in the OP-LAMP2 group was higher in the OP-LAMP2 group compared to the EP group, and lower in the siLAMP2 group compared to the siLAMP2-NC group, while the relative expression of negatively regulated autophagy genes followed the opposite trend to that of autophagy positively regulated genes. The relative expression of autophagy-related proteins was consistent with the trend of autophagy genes. Conclusions miR-207 enhances macrophage apoptosis, cellular pyroptosis and inhibits autophagy, promoting survival of Mycobacterium tuberculosis by targeting the autophagy-related protein LAMP2, thus offering a novel therapeutic direction for tuberculosis.

Objective To investigate the impact of Qizhi Jiangtang Capsule (QZJT) on renal damage in diabetic nephropathy (DN) mice via NOD like receptors family pyrin domain containing 3/caspase-1/ Gasdermin D (NLRP3/caspase-1/GSDMD) signaling pathway. Methods Mice were randomly allocated into six experimental groups: a normal control group (NC), a diabetic nephropathy model group (DN), a low-dose QZJT treatment group (L-QZJT), a high-dose QZJT treatment group (H-QZJT), a positive control group administered Shenqi Jiangtang Granules (SQJT), and an ML385 group (treated with an inhibitor of nuclear factor erythroid 2-related factor 2, Nrf2). Upon successful model induction, therapeutic interventions were commenced. Renal function impairment in the mice was evaluated through quantification of fasting blood glucose (FBG), 24-hour urinary albumin (UAlb), serum creatinine (SCr), blood urea nitrogen (BUN), and the kidney-to-body mass ratio (K/B). Renal tissue pathology was evaluated using HE and PAS staining. Serum levels of inflammatory cytokines IL-1β and IL-18 were quantified by ELISA. Levels of podocyte markers and proteins involved in relevant pathways were assessed using Western blot analysis. Results Compared with the NC group, FBG, 24 h UAlb, SCr, and BUN were increased in the DN group, and the K/B mass ratio was also increased. In contrast, compared with the DN group, FBG, 24 h UAlb, SCr, and BUN in both the low-dose (L-QZJT) and high-dose Quanzhou Jintang (H-QZJT) groups were decreased, and the K/B mass ratio was decreased as well. The therapeutic efficacy of H-QZJT was comparable to that of Shenqi Jiangtang Granules. QZJT ameliorated renal histopathological injury in DN mouse, increased the protein levels of Nephrin (a podocyte marker), and decreased the protein levels of NLRP3, apoptosis-associated speck-like protein containing CARD (ASC), pro-caspase-1, and GSDMD-N. After ML385 treatment, renal cells exhibited swelling and morphological changes, the inflammatory infiltrate area was enlarged, the protein levels of NLRP3, ASC, pro-caspase-1, and GSDMD-N were up-regulated, and the levels of IL-1β and IL-18 were increased. Conclusion QZJT may inhibit podocyte pyroptosis by acting on the Nrf2 to regulate the NLRP3/caspase-1/GSDMD pathway, thus improving renal damage in DN mouse.

Objective To investigate the effects of exosomes (Exo) derived from high glucose-stimulated glomerular mesangial cells (GMC) on the kidneys of C57BL/6 mice and the intervention mechanism of Tongluo Yishen Formula (TLYSF). Methods The rat GMC were divided into a normal glucose group (NG, with 5.6 mmol/L glucose) and a high glucose group (HG, with 30 mmol/L glucose). After 24 hours of culture, the supernatant was collected, and exosomes were extracted using the ultracentrifugation method. The exosomes were then identified by transmission electron microscopy and Western blot analysis. Male C57BL/6 mice were divided into three groups: NO-Exo group, NG-Exo group, and HG-Exo group. These groups were respectively administered tail vein injections of PBS buffer, exosomes derived from GMC cultured in normal glucose, and exosomes derived from GMC cultured in high glucose, three times a week for a total of 8 weeks. After 8 weeks, the mice in the HG-Exo group were randomly divided into three subgroups: the HG-Exo group [gavaged with saline], the HG-Exo+TLYSF group [gavaged with TLYSF at 34.32 g/(kg.d)], and the HG-Exo + VAL group [gavaged with valsartan suspension at 10.4 mg/(kg.d)], and the intervention lasted for 4 weeks. Urinary microalbumin (mALb), urinary N-acetyl-β-D-aminoglucosidase (NAG), glycated hemoglobin (HbA1c), serum creatinine (Scr) and urea nitrogen (BUN) were detected. Transmission electron microscopy was used to observe the ultrastructure of renal tissues. TUNEL was used to detect the DNA damage of renal tissue cells. Immunofluorescence was used to detect the expression of NOD-like receptor family pyrin domain containing 3 (NLRP3) and wilms tumor 1(WT-1). RT-PCR was used to detect the mRNA levels of NLRP3, cysteinyl aspartate-specific proteinase 1 (caspase-1), interleukin-1 beta (IL-1β), miR-200c-3p and miR-148a-3p. Western Blot was employed to detect the protein expression of NLRP3, apoptosis-associated speck-like protein containing a CARD (ASC), caspase-1 and IL-1β. Results Compared with the NG-Exo group, mice in the HG-Exo group exhibited significantly increased levels of mALb, urinary NAG, Scr and BUN. Transmission electron microscopy revealed ruptured podocyte membranes and swollen mitochondria. The positive rate of cells stained by the TUNEL increased, with elevated optical density of NLRP3 and decreased optical density of WT-1. Additionally, there was a significant increase in the level of NLRP3, caspase-1, IL-1β mRNA, as well as miR-200c-3p and miR-148a-3p. The protein expression of NLRP3, ASC, caspase-1, and IL-1β also increased. Compared with HG-Exo group, mice in the HG-Exo+TLYSF group showed decreased levels of mALb, urinary NAG, Scr, and BUN. The podocyte membranes were relatively intact, and mitochondrial damage was alleviated. The positive rate of cells stained by the TUNEL decreased, along with a reduction in the optical density of NLRP3 and an increase in the optical density of WT-1. Furthermore, the mRNA expression levels of NLRP3, caspase-1, IL-1β, miR-200c-3p, and miR-148a-3p were all downregulated to varying degrees. The protein expression levels of NLRP3, ASC, caspase-1, and IL-1β also decreased. Conclusion Exosomes derived from GMC stimulated by high glucose can damage the kidneys of mice and induce podocyte pyroptosis. TLYSF may ameliorate podocyte pyroptosis by downregulating the expression of exosomal miR-200c-3p and miR-148a-3p and inhibiting the activation of the NLRP3/ASC/caspase-1 pathway.

Paramyxoviruses are important respiratory pathogens with substantial clinical relevance in pediatric infectious diseases. During infection, multiple forms of programmed cell death (PCD) may be induced, and this plays pivotal roles in viral replication, dissemination, and host immune responses, thereby profoundly influencing the viral life cycle and disease progression. On one hand, PCD facilitates the clearance of infected cells, restricts viral spread, and activates host immune defenses, thereby enhancing antiviral immunity. On the other hand, excessive or dysregulated cell death may lead to tissue damage and immune imbalance, creating a microenvironment conducive to viral replication and exacerbating disease severity. For instance, apoptosis-mediated by both extrinsic and intrinsic pathways-contributes to infection control but may also be hijacked by viruses to promote dissemination. Pyroptosis, driven by inflammasome activation, triggers lytic cell death and the release of pro-inflammatory cytokines. Necroptosis, mediated by the RIPK1-RIPK3-MLKL signaling axis, and pyroptosis both amplify innate immune responses but may concurrently induce inflammatory dysregulation. Immunogenic cell death (ICD), characterized by the release of damage-associated molecular patterns and neoantigens, activates antigen-specific immune responses and holds therapeutic potential for antiviral and antitumor interventions. Emerging evidence suggests that ferroptosis, through the modulation of iron metabolism and associated transporters, may also participate in viral replication and infected cell clearance. This review comprehensively summarizes the roles of apoptosis, pyroptosis, necroptosis, ICD, and ferroptosis in paramyxovirus infection, aiming to deepen the understanding of paramyxovirus pathogenesis and to provide insights for developing novel antiviral strategies.

This paper investigated the inhibitory effect of carbonized Scutellariae Radix(Cb-SR) on pyroptosis in endometrial epithelial cells of mice with endometritis and its correlation with the IKBKE/NLRP3 signaling axis. Mice model of endometritis was established by using an intrauterine injection of 10 μL polysaccharides(LPS, 5 mg·mL~(-1)), and the mice were randomly divided into model group(LPS), low-dose group of Cb-SR(L-Cb-SR, 0.55 g·kg~(-1)), medium-dose group of Cb-SR(M-Cb-SR, 1.10 g·kg~(-1)), high-dose group of Cb-SR(H-Cb-SR, 2.20 g·kg~(-1)), crude Scutellariae Radix group(Cr-SR, 1.63 g·kg~(-1)), and Fuke Qianjin Capsule group(FQC, 0.30 g·kg~(-1)), with 10 mice in each group. Ten healthy female mice were selected and injected with PBS of equal volume into the bilateral uterus, and they were set as the sham group. The mice in the drug treatment groups were given the corresponding doses of Cb-SR, Cr-SR, FQC, or physiological saline of equal volume by gavage twice a day for seven days. Thirty minutes after the last administration, each mouse was euthanized by cervical dislocation. Hematoxylin-eosin(HE) staining and transmission electron microscopy were applied to observe the histopathological morphology of the uterine tissue. Immunohistochemistry was used to detect the expression of CD38 and CD138. Myeloperoxidase(MPO) values in neutrophils were measured by the kit; Enzyme-linked immunosorbent assay(ELISA) was used to measure the secretion of interleukin-18(IL-18), interleukin-1β(IL-1β), and tumor necrosis factor-α(TNF-α). Immunofluorescence and Western blot were used to analyze the expression of the proteins related to the IKBKE/NLRP3 signaling axis. Mouse endometrial epithelial cells(MEECs) were separated and purified from the uterine tissue of pregnant female mice through in vitro experiments and injured by LPS for 24 h, and then they were cultured with Cb-SR-containing serum. The anti-endometritis effect of Cb-SR was investigated by CCK-8 assay, scanning electron microscopy, and Western blot. The results showed that Cb-SR significantly reduced MPO values, attenuated uterine tissue damage, inhibited the expression of CD38 and CD138, decreased the levels of IL-1β, IL-18, and TNF-α, and inhibited the expression of proteins associated with IKBKE/NLRP3 signaling axis in mice with endometritis. In addition, Cb-SR-containing serum reduced swelling of MEECs organelles induced by LPS, decreased the expression of inflammatory factors, and suppressed the expression of IKBKE/NLRP3 signaling axis-related proteins. These results suggest that Cb-SR can inhibit endometrial epithelial cell pyroptosis in endometritis by suppressing the IKBKE/NLRP3 signaling axis.

This study aims to explore the intervention effects of isorhamnetin(Isor) on acute lung injury(ALI) and its regulatory effects on pyroptosis mediated by the NOD-like receptor family pyrin domain containing 3(NLRP3)/apoptosis-associated speck-like protein containing a CARD(ASC)/cysteine aspartate-specific protease-1(caspase-1) axis. In the in vivo experiments, 60 BALB/c mice were divided into five groups. Except for the control group, the other groups were administered Isor by gavage 1 hour before intratracheal instillation of LPS to induce ALI, and tissues were collected after 12 hours. In the in vitro experiments, RAW264.7 cells were divided into five groups. Except for the control group, the other groups were pretreated with Isor for 2 hours before LPS stimulation and subsequent assessments. Hematoxylin-eosin(HE) staining was used to observe pathological changes in lung tissue, while lung swelling, protein levels in bronchoalveolar lavage fluid(BALF), and myeloperoxidase(MPO) levels in lung tissue were measured. Cell proliferation toxicity and viability were assessed using the cell counting kit-8(CCK-8) method. Enzyme-linked immunosorbent assay(ELISA) was used to detect the levels of interleukin-1β(IL-1β), IL-6, IL-18, and tumor necrosis factor-α(TNF-α). Protein levels of NLRP3, ASC, cleaved caspase-1, and the N-terminal fragment of gasdermin D(GSDMD-N) were evaluated using immunohistochemistry, immunofluorescence, and Western blot. The results showed that in the in vivo experiments, Isor significantly improved pathological damage in lung tissue, reduced lung swelling, protein levels in BALF, MPO levels in lung tissue, and levels of inflammatory cytokines such as IL-1β, IL-6, IL-18, and TNF-α, and inhibited the high expression of the NLRP3/ASC/caspase-1 axis and the pyroptosis core gene GSDMD-N. In the in vitro experiments, the safe dose of Isor was determined through cell proliferation toxicity assays. Isor reduced cell death and inhibited the expression levels of the NLRP3/ASC/caspase-1 axis, GSDMD-N, and inflammatory cytokines. In conclusion, Isor may alleviate ALI by modulating pyroptosis mediated by the NLRP3/ASC/caspase-1 axis.

This study aims to investigate the therapeutic effects of the Coptidis Rhizoma-Scutellariae Radix on cytokine storm secondary lung injury(CSSLI) induced by CpG1826 in mice, and to elucidate the potential molecular mechanisms by which its major active components, i.e., coptisine and wogonin, alleviate CSSLI by inhibiting the mitochondrial permeability transition pore(mPTP)/nucleotide-binding oligomerization domain-like receptor protein 3(NLRP3) inflammasome pyroptosis pathway. In vivo, a mouse model of CSSLI was established by CpG1826 induction. Pulmonary edema was assessed by lung wet-to-dry weight ratio(W/D), lung injury was evaluated by hematoxylin-eosin(HE) staining, and ultrastructural changes in lung tissue were observed by transmission electron microscopy(TEM). The levels of interleukin(IL)-1β, high mobility group box 1 protein(HMGB1), IL-18, and IL-1α in bronchoalveolar lavage fluid were measured by enzyme-linked immunosorbent assay(ELISA). The results showed that the decoction of the Coptidis Rhizoma-Scutellariae Radix significantly reduced pulmonary edema, alleviated lung injury, and decreased the concentrations of related cytokines in BALF more effectively than either single herb alone, thereby improving CSSLI. In vitro, a CpG1826-induced CSSLI model was established in mouse alveolar macrophage MH-S cells. Calcein-AM quenching was used to screen for the most effective monomer components from the herb pair in inhibiting mPTP opening. Coptisine(5, 10, 20 μmol·L~(-1)) and wogonin(10, 20, 40 μmol·L~(-1)) markedly inhibited mPTP opening, with optimal effects and a clear dose-dependent pattern. These components suppressed mPTP opening, thereby reducing the release of mitochondrial DNA(mtDNA) and the accumulation of reactive oxygen species(ROS), effectively reversing the CpG1826-induced decrease in mitochondrial membrane potential(MMP). Further studies revealed that both coptisine and wogonin inhibited pyroptosis and downregulated the expression of key proteins in the NLRP3/Caspase-1/gasdermin D(GSDMD) pathway. In conclusion, the Coptidis Rhizoma-Scutellariae Radix improves CpG1826-induced CSSLI in mice, and this effect is associated with the inhibition of the mPTP/NLRP3 pyroptosis pathway, providing scientific evidence for its clinical application and further development.
