Innate and adaptive immunity

The immune system is the body’s defense system that protects us from foreign (non-self) substances. The immune system assumes foreign things are dangerous as they are usually pathogens like bacteri…

Interleukin-12 (IL-12) is a heterodimeric pro-inflammatory cytokine that induces the production of interferon-γ (IFN-γ), favours the differentiation of T helper 1 (TH1) cells and forms a link between innate resistance and adaptive immunity. Dendritic cells (DCs) and phagocytes produce IL-12 in response to pathogens during infection. Production of IL-12 is dependent on differential mechanisms of regulation of expression of the genes encoding IL-12, patterns of Toll-like receptor (TLR)…

Acquired (adaptive or specific) immunity is a type of immunity that develops when a person’s immune system responds to a foreign substance or microorganism, or that occurs after a person receives antibodies from another source, Types of acquired immunity are adaptive and passive, Adaptive immunity occurs in response to being infected with or vaccinated against a microorganism.

Innate Immunity is present right from the birth but acquired or adaptive immunity is acquired during the course of life.

Just as resistance to disease can be innate (inborn) or acquired, the mechanisms mediating it can be correspondingly divided into innate (left) and adaptive (right), each composed of both cellular (lower half) and humoral elements (i.e. free in serum or body fluids; upper half). Adaptive mechanisms, more recently evolved, perform many of their functions by interacting with the older innate ones. Innate immunity is activated when cells use specialized sets of receptors (see Fig. 5) to…

Practicing a healthy diet is among the best ways to ensure a healthy immune system. Eating foods with proper vitamins & minerals can help support overall health.

What is the difference between Innate and Adaptive Immunity? Innate immunity generates a non-specific immune response, but adaptive immunity generates a ...
