Article Abstract
The entry of SARS-CoV-2 into host cells is dependent upon angiotensin-converting enzyme 2 (ACE2), which serves as a functional attachment receptor for the viral spike glycoprotein, and the serine protease TMPRSS2 which allows fusion of the viral and host cell membranes. We devised a quantitative measure to estimate genetic determinants of ACE2 and TMPRSS2 expression and applied this measure to >2500 individuals. Our data show significant variability in genetic determinants of ACE2 and TMPRSS2 expression among individuals and between populations, and indicate a genetic predisposition for lower expression levels of both key viral entry genes in African populations. These data suggest that host genetics related to viral entry mechanisms might influence interindividual variability in disease susceptibility and severity of COVID-19.

DMBT1 is a large scavenger receptor cysteine rich (SRCR) B protein that has been reported as a tumor suppressor gene and a co-receptor for HIV-1 infection. Here we found DMBT1 is a major mucosal protein bound to SARS-CoV-2. Overexpression of DMBT1 in 293T cells may enhanced infection by SARS-CoV-2 in ACE2 dependent manner.

The emergence of Severe Acute Respiratory Syndrome Coronavirus 2 (SARS-CoV-2) as the causative agent of COVID-19 precipitated a global health crisis of unprecedented scale. SARS-CoV-2 has been shown to interfere specifically with S phase progression during early stages of infection. Nucleocapsid (N) is an important structural protein.

Unlabelled: Ongoing viral evolution in immunocompromised individuals with persistent infection may facilitate the evolution of SARS-CoV-2 and emergence of variants of concern (VOC). This study was conducted in the Western Cape Province of South Africa where the HIV prevalence is around 8%, with limited information on the frequency of persistent SARS-CoV-2 infection, the pattern of evolution in these individuals, and if these variants contribute to the diversity of circulating viruses. This study investigated 75 individuals with two or more SARS-CoV-2 diagnoses at least one month apart.

RNA viruses have high mutation frequency, quick generation periods and vast population numbers, which promote fast evolution and host environment adaptation. We integrated scRNA-seq and spatial transcriptomics to profile immune cells and viral gene expression in COVID-19. Cell types and interactions were identified using Seurat-based tools.

Although direct-acting antivirals have shown success, their efficacy is limited by the rapid emergence of drug-resistant viral variants. Hence, there is an urgent need for additional broad spectrum antiviral therapeutic strategies.
