To compare the effectiveness and safety profile of tenofovir amibufenamide (TMF) and tenofovir alafenamide (TAF), especially the effects on lipid metabolism in the treatment of chronic hepatitis B. A retrospective study was conducted on the virological response rate, biochemical response rate, renal function indicators, and lipid metabolism status of 159 cases with chronic hepatitis B (72 cases with TMF and 87 cases with TAF) after 48 weeks of antiviral treatment. The effects of the two drugs on lipid metabolism were further explored through cell and animal experiments.

Porcine reproductive and respiratory syndrome virus (PRRSV) is a highly contagious swine pathogen, causing respiratory problems in piglets and reproductive failure in sows. Palmitoylation, catalyzed by zinc finger Asp-His-His-Cys (ZDHHC) domain-containing palmitoyl acyltransferases, plays intricate roles in virus infection. However, whether palmitoylation regulates PRRSV replication is incompletely understood.

HBV genotype A has two major subtypes, A1 (commonly in Africa) and A2 (commonly in Europe) with only 4% nucleotide differences. Individuals infected with these two subtypes appear to have different clinical manifestations and virologic features. Whether such a difference results from the virus or host has not been established.

Parainfluenza virus type 5 (PIV5) can cause either persistent or acute/lytic infections in a wide range of mammalian tissue culture cells. Here, we have generated PIV5 fusion (F)-expressing helper cell lines that support the replication of F-deleted viruses. As proof of the principle that F-deleted single-cycle infectious viruses can be used as safe and efficient expression vectors, we have cloned and expressed a humanized (Hu) version of the mouse anti-V5 tag antibody (clone SV5-Pk1).

Background: Effective treatment for patients with metastatic cancer is limited, particularly for colorectal cancer patients with metastatic liver lesions (mCRC), where accessibility to numerous tumours is essential for favourable clinical outcomes. Oncolytic viruses (OVs) selectively replicate in cancer cells; however, direct targeting of inaccessible lesions is limited when using conventional intravenous or intratumoural administration routes.
Methods: We conducted a multi-centre, dose-escalation, phase I study of vaccinia virus, TG6002, via intrahepatic artery (IHA) delivery in combination with the oral pro-drug 5-fluorocytosine to fifteen mCRC patients.
