Modulation of cellular autophagy by genotype 1 hepatitis E virus ORF3 protein.

Hepatitis E virus (HEV) egresses from infected hepatocytes as quasienveloped particles containing open reading frame 3 (ORF3) protein. HEV ORF3 (small phosphoprotein) interacts with host proteins to establish a favourable environment for virus replication. It is a functional viroporin that plays an important role during virus release.

DNAJB8 facilitates autophagic-lysosomal degradation of viral Vif protein and restricts HIV-1 virion infectivity by rescuing APOBEC3G expression in host cells.

HSP40/DNAJ family of proteins is the most diverse chaperone family, comprising about 49 isoforms in humans. Several reports have demonstrated the functional role of a few of these isoforms in the pathogenesis of various viruses, including HIV-1. Our earlier study has shown that several isoforms of HSP40 get significantly modulated at the mRNA level during HIV-1 infection in T cells.

Zipper interacting protein kinase (ZIPK) is a negative regulator of HIV-1 replication that is restricted by viral Nef protein through proteasomal degradation.

Human immunodeficiency virus-1 (HIV-1) infection leads to the development of acquired immunodeficiency syndrome (AIDS). To establish a productive infection, HIV-1 hijacks the cellular machinery and modulates various physiological processes to propagate itself. The pathways altered by HIV-1 include cell cycle, autophagy, apoptosis, cell stress pathways, immune response, antiviral response, etc.

The novel SARS-CoV-2 pandemic: Possible environmental transmission, detection, persistence and fate during wastewater and water treatment.

The contagious SARS-CoV-2 virus, responsible for COVID-19 disease, has infected over 27 million people across the globe within a few months. While literature on SARS-CoV-2 indicates that its transmission may occur predominantly via aerosolization of virus-laden droplets, the possibility of alternate routes of transmission and/or reinfection via the environment requires considerable scientific attention. This review aims to collate information on possible transmission routes of this virus, to ascertain its fate in the environment.
