Objective To investigate the in vitro anti-hepatitis B virus(HBV)effects of icariside Ⅱ(ICS Ⅱ)and its impact on mitochondrial fission.Methods HBV-positive hepatocellular carcinoma HepAD38 cells were used as the cellular model.The cytotoxicity of ICS Ⅱ was assessed via CCK8 assay.The secretion levels of HBV surface antigen(HBsAg)and HBV e antigen(HBeAg),as well as HBV DNA copy numbers,were measured by ELISA and qPCR after treatment with ICS Ⅱ alone or ICS Ⅱ in combination with entecavir(ENT).The effects of ICS Ⅱ on mitochondrial morphology and motility were observed using confocal laser scanning microscopy and transmission electron microscopy(TEM).After ICS Ⅱ treatment,Western blot was performed to analyze the expression levels of key proteins involved in mitochondrial dynamics.Additionally,intracellular reactive oxygen species(ROS)production was evaluated via fluorescence staining.Results The CCK8 assay results showed that ICS Ⅱ treatment at 25 μmol/L had no significant effect on cell proliferation after 72 h.ICS Ⅱ significantly inhibited the secretion levels of HBsAg and HBeAg,with the respective inhibition rates reaching 54.90%and 39.65%(P<0.05).Additionally,ICS Ⅱ alone reduced HBV DNA copy numbers by 15.19%,while ENT alone achieved a 34.11%inhibition rate.Notably,ICS Ⅱ in combination with ENT reduced HBV DNA copy numbers by 55.81%(P<0.05).Furthermore,ICS Ⅱ induced mitochondrial shortening and enhanced mitochondrial motility in HepAD38 cells(P<0.05).ICS Ⅱ significantly increased the expression levels of mitochondrial motility-related proteins,including Mfn1,Fis1,and phosphorylated Drp1(ser 616)(P<0.05),while no significant changes were observed in the expression levels of Mfn2,total Drp1,or Drp1(ser 637)(P>0.05).Additionally,ICS Ⅱ significantly suppressed the production of intracellular ROS in HepAD38 cells(P<0.05).Conclusion ICS Ⅱ inhibits HBV replication in HepAD38 cells,and the underlying mechanism may be associated with the promotion of mitochondrial fission and suppression of ROS production.

Infectious keratitis (IK) is a leading cause of blindness worldwide, primarily resulting from improper contact lens use, trauma, and a compromised immune response. The pathogenic microorganisms responsible for IK include bacteria, fungi, viruses, and Acanthamoeba. This review examines standard therapeutic agents for treating IK, including broad-spectrum empiric antibiotics for bacterial keratitis (BK), antifungals such as voriconazole and natamycin for fungal infections, and antiviral nucleoside analogues for viral keratitis (VK). Additionally, this review discusses therapeutic agents, such as polyhexamethylene biguanide (PHMB), for the treatment of Acanthamoeba keratitis (AK). The review also addresses emerging drugs and the challenges associated with their clinical application, including anti-biofilm agents that combat drug resistance and nuclear factor kappa-B (NF-κB) pathway-targeted therapies to mitigate inflammation. Furthermore, methods of Photodynamic Antimicrobial Therapy (PDAT) are explored. This review underscores the importance of integrating novel and traditional therapies to tackle drug resistance and enhance drug delivery, with the goal of advancing treatment strategies for IK.

Objective:To identify the CDYL-interacting proteins in murine testis and investigate the mechanism of CDYL in-volved in spermatogenesis.Methods:CDYL-interacting partners in testis were identified using co-immunoprecipitation coupled with liquid chromatography-tandem mass spectrometry(LC-MS/MS).Expression pattern of CDYL-interacting protein MYH9 was analyzed through immunohistochemistry(IHC),confocal immunofluorescence(IF)and Western blot(WB)in mouse testicular cells.The effect of the Cdyl conditional knockout(CdylcKO)in spermatogenic cell on Myh9 expression was quantified via RT-qPCR,WB and IF imaging in both spermatids and spermatozoa from cauda epididymides.Results:Direct interaction between MYH9 and CDYL was confirmed in murine testis.During spermiogenesis,MYH9 exhibited co-localization with CDYL at the manchette structure,and binding to F-ACTIN,the component of manchette.In cauda epididymal spermatozoa,MYH9 signal concentrated on acrosomal region and con-tinuously distributed along the tail length.Conditional deletion of Cdyl in spermatogenic cell resulted in the transcriptional downregula-tion of Myh9.In spermatids,CdylcKO led to reduced but retained MYH9 localization to the disorganized manchette structure.In sperma-tozoa from CdylcKO mice,abnormalities of MYH9 localization were observed,including attenuation of acrosomal signal and/or partial vanishment/enhancement of tail signal.Conclusion:In murine spermatids,MYH9 protein is localized to the manchette structure,with its expression and subcellular distribution is affected by CDYL protein.CDYL-MYH9 interaction is essential for the spermiogenesis.
