The contagiosity of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) has startled mankind and has brought our lives to a standstill.The treatment focused mainly on repurposed immunomodulatory and antiviral agents along with the availability of a few vaccines for prophylaxis old taylor whiskey 1933 price to vanquish COVID-19.This seemingly mandates a deeper understanding of the disease pathogenesis.This necessitates a plausible extrapolation of cell-based therapy to COVID-19 and is regarded equivalently significant.Recently, correlative pieces of clinical evidence reported a robust decline in lymphocyte count in severe COVID-19 patients that suggest dysregulated immune responses as a key element contributing to the pathophysiological alterations.
The large granular lymphocytes also known as natural killer (NK) cells play a heterogeneous role in biological functioning wherein their frontline action defends the body against a wide array of infections and tumors.They prominently play a critical role in viral clearance and executing immuno-modulatory activities.Accumulated clinical evidence demonstrate a decrease in the number of NK cells in circulation with or without phenotypical exhaustion.These plausibly contribute to the progression of pulmonary inflammation in COVID-19 pneumonia and result in acute lung injury.In this review, we have outlined the present understanding of the immunological response of NK cells in COVID-19 infection.
We have also discussed the possible use of these powerful biological cells as a therapeutic kicker pro comp 10 agent in view of preventing immunological harms of SARS-CoV-2 and the current challenges in advocating NK cell therapy for the same.
