Numerous variants of the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) pandemic have evolved. Viral may evolve with harmful susceptibility to immunity established existing COVID-19 vaccination. These are more transmissible, induce relatively extreme illness, evasive immunological features, decrease neutralization using antibodies from vaccinated persons, and susceptible re-infection. The Centers for Disease Control Prevention (CDC) has categorized SARS-CoV-2 mutations as interest (VOI), concern (VOC), high consequence (VOHC). At moment, four VOC many been defined require constant observation. This review article summarizes various surfaced special emphasis on VOCs that spreading across world, well several viral mutational impacts how these modifications alter properties virus.

Abstract Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), showing high infectiousness, resulted in an ongoing pandemic termed disease 2019 (COVID-19). COVID-19 cases often experience distress syndrome, which has caused millions of deaths. Apart from triggering inflammatory and immune responses, many viral infections can cause programmed cell death infected cells. Cell mechanisms have a vital role maintaining suitable environment to achieve normal functionality. Nonetheless, these processes are dysregulated, potentially contributing pathogenesis. Over the past decades, multiple pathways becoming better understood. Growing evidence suggests that induction by may significantly contributes infection pathogenicity. However, interaction SARS-CoV-2 with death, together its associated mechanisms, is yet be elucidated. In this review, we summarize existing concerning molecular modulation as well viral-host interactions, shed new light on antiviral therapy against SARS-CoV-2.

Abstract Severe acute respiratory syndrome coronavirus 2 (SARS‐CoV‐2) dysregulates antiviral signaling, immune response, and cell metabolism in human body. Viral genome proteins hijack host metabolic network to support viral biogenesis propagation. However, the regulatory mechanism of SARS‐CoV‐2‐induced dysfunction has not been elucidated until recently. Multiomic studies disease 2019 (COVID‐19) revealed an intensive interaction between regulators proteins. SARS‐CoV‐2 deregulated cellular blood, intestine, liver, pancreas, fat, cells. Host supported almost every stage lifecycle. Strikingly, were found interact with enzymes different compartments. Biochemical genetic assays also identified key nodes dependencies replication. Of note, cholesterol metabolism, lipid glucose are broadly involved Here, we summarized current understanding hallmarks COVID‐19 metabolism. infection remodels which turn modulates Remodeling creates vulnerability replication, could be explored uncover new therapeutic targets. The efficacy inhibitors against is under investigation several clinical trials. Ultimately, knowledge reprogramming would accelerate drug repurposing or screening combat pandemic.
