Abstract:
The cellular innate immune system plays a crucial role in mounting the initial resistance to virus infection. It is comprised of various pattern-recognition receptors that induce type I interferon production, which further shapes the adaptive immunity. However, to overcome this resistance and promote replication, viruses have evolved mechanisms to evade this host innate immune response. Here we discuss a recently described mechanism of boosting the innate immunity by oligoadenylate synthetase-like (OASL) protein, which can potentially be used to overcome viral evasion and enhance innate immunity.

NK Cells
NK cells are a crucial part of our innate immune system, acting as the first line of defense against viral infections. These cells can recognize and kill infected cells without prior exposure to the virus, effectively slowing down the spread of infection. Additionally, NK cells produce proinflammatory...

Introduction to Innate and Adaptive Immunity
Innate immunity is the body's natural, nonspecific defense system that acts quickly to protect against pathogens. It incorporates physical barriers like skin and mucous membranes and cellular elements such as phagocytes and natural killer cells. This part of our immune system provides an immediate,...
