Researchers identify glucosidase alpha, neutral C (GANC) as a host factor in #H7N9; rare variants reduce #ViralReplication, while GANC knockdown limits #InfluenzaA via proteasome‑dependent #hemagglutinin degradation.

While people with well-controlled #HIV on effective antiretroviral therapy (ART) generally 🦠 effectively, advanced immunodeficiency can lead to prolonged #viralreplication, shedding, & evolution. This creates a favourable environment for the generation of novel, potentially drug-resistant variants.

As further experiments revealed that they also help redirect carbon flux towards #nucleotidesynthesis, ultimately fuelling #viralreplication.
Viral folate genes are often thought to aid in cofactor biosynthesis. Folate is also used for de novo nucleotide biosynthesis

Pp1ab is a large non-structural protein in #SARSCoV2, crucial for #viralreplication & transcription. It is unique to #SARSCoV2 & not found in uninfected human cells. After being translated from the #viralRNA, Pp1ab is cleaved into 16 nonstructural proteins (nsps)

Exciting days at the Italian Society for Virology Congress in Turin🇮🇹 to talk about the new frontiers in #viralreplication factory biology. 🔬Inspiring to exchange ideas and build new collaborations with talented early-career virologists 🦠 #SIVISV2025

study shows that lower and upper respiratory tract infection can lead to systemic #viralreplication, 🦠 shedding & pneumonia with varying degrees of disease outcome In contrast, orogastric exposure led to virus infection, reduced 🦠 shedding & subclinical disease

#MedSky🧪#IDsky #ImmunoSky Historically, strategies to combat #influenza 🦠 have focused on preventing or reducing #viralreplication. The mechanism for targeting influenza disease that is decoupled from 🦠 replication by harnessing an anti-inflammatory IgG-FcγR signaling pathway.

An oral non-covalent non-peptidic inhibitor of SARS-CoV-2 Mpro ameliorates viral replication and pathogenesis in vivo Zhou et al. describe NZ-804, a non-peptidic inhibitor of the SARS-CoV-2 Mpro. It shows potent antiviral activity with low-nanomolar IC50 and EC50 in human lung cells and primary airway epithelial cult...
