Abstract:
Type I Interferons are the hallmark cytokines deployed during infection to combat invading viruses. However, inflammatory cytokines such as Interleukin (IL)-1beta and IL-18 also play important roles in anti-viral defenses. The activity of IL-1beta and IL18 are regulated at the level of expression, processing, and secretion. Several classes of innate immune receptors control the expression of these cytokines, which must then be proteolytically processed via caspase-1. In this review, we provide an overview of how caspase-1-activating inflammasomes participate during viral infections and their role in regulating anti-viral immunity.

Immune Response Against Viral Pathogens
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...

Antibody Structure
Antibodies, also known as immunoglobulins (Ig), are essential players of the adaptive immune system. These antigen-binding proteins are produced by B cells and make up 20 percent of the total blood plasma by weight. In mammals, antibodies fall into five different classes, which each elicits a different biological response upon antigen binding.

Antibody Structure and Classes
The basic structure of an antibody consists of four protein chains: two identical heavy chains and two identical light chains. These chains are held together by disulfide bonds and other non-covalent interactions, forming a Y-shaped structure.
