Lysosomes represent a promising target for cancer therapy and reducing drug resistance. However, the short treatment time and low efficiency of lysosomal targeting have limited the application in lysosome-targeting anticancer drugs. In this study, we proposed an adhesive-bandage approach and synthesized a new lysosomal targeting drug, namely long-term lysosome-targeting anticancer drug (LLAD). It contains a SLC38A9-targeting covalently bound moiety and an alkaline component both to prolong the inhibition of SLC38A9 in lysosomes and alkalinize lysosomes. Upon short term and low-dose treatment of HeLa cells, at passage 0, with LLAD, it rapidly alkalinized lysosomes and also can be detected in lysosomes even at passage 15. LLAD induced apoptosis in HeLa cells through long-term lysosomal damage, and showed better long-term anticancer effect than cisplatin in vivo. Overall, our study paves the way for developing long-term lysosomal targeting drugs to treat cancer and overcome the drug resistance of cancer cells, and also provides a candidate drug, LLAD, for treating cancer.

Objective:To analyze and summarize the clinical characteristics of mpox patients, thereby to rise clinicians′ awareness of severe mpox and provide a foundation for clinical diagnosis and treatment.Methods:The clinical data were retrospectively analyzed in 41 mpox patients treated at the Beijing You′an Hospital, Capital Medical University, from June to November 2023. Patients were categorized into mild and severe cases based on clinical manifestations, and laboratory results of the two groups were compared. Statistical analysis was performed using the Mann-Whitney U test. Results:The clinical manifestations of 41 mpox patients mainly included fever, rash and lymphadenopathy. Five patients with severe mpox might develop serious complications, including bacterial pneumonia, type Ⅰ respiratory failure, fungal infections, penile or perianal dry gangrene, penile soft tissue edema, intestinal obstruction, septic shock, perianal abscess, and necrotizing fasciitis. Patients with severe mpox had significantly higher white blood cell count (WBC), neutrophil count and C-reactive protein (CRP) level compare to those with mild cases (14.60(9.92, 24.08)×10 9/L vs 6.41(5.64, 8.37)×10 9/L, 12.43(7.02, 21.15)×10 9/L vs 3.35(2.46, 5.03)×10 9/L, 108.20(56.20, 124.10) mg/L vs 16.6(6.25, 49.98) mg/L), while the albumin level and CD4 + T lymphocyte count in the severe group were significantly lower compared to the mild cases (31.80(22.90, 35.15) g/L vs 44.70(42.90, 47.40) g/L, 24.00(12.00, 81.50)/μL vs 606.00(414.50, 767.50)/μL)). All these differences were statistically significant ( U=2.81, 3.02, 2.98, 3.56 and 3.26, respectively, all P<0.01). Conclusions:In clinical practice, clinicians should be vigilant for the possibility of severe mpox if patients exhibit a significant increase of WBC and CRP, a significant decrease in CD4 + T lymphocyte count, or if they develop severe complications.

Decellularized matrix transplantation has emerged as a promising therapeutic approach for repairing tissue defects, with numerous studies assessing its safety and efficacy in both animal models and clinical settings. The host immune response elicited by decellularized matrix grafts of natural biological origin plays a crucial role in determining the success of tissue repair, influenced by matrix heterogeneity and the inflammatory microenvironment of the wound. However, the specific immunologic mechanisms underlying the interaction between decellularized matrix grafts and the host immune system remain elusive. This article reviews the sources of decellularized matrices, available decellularization techniques, and residual immunogenic components. It focuses on the host immune response following decellularized matrix transplantation, with emphasis on the key mechanisms of Toll-like receptor, T-cell receptor, and TGF-β/SMAD signaling in the stages of post-transplantation immunorecognition, immunomodulation, and tissue repair, respectively. Furthermore, it highlights the innovative roles of TLR10 and miR-29a-3p in improving transplantation outcomes. An in-depth understanding of the molecular mechanisms underlying the host immune response after decellularized matrix transplantation provides new directions for the repair of tissue defects.
