Question

Why does innate and adaptive immunity work in cooperative manner?

Answer 1

The interaction between innate and adaptive immunity is mediated by a type of phagocyte called a dendritic cell. These cells are multifunctional; they can detect pathogens and activate an innate response, eliminate pathogens through phagocytosis and, uniquely, activate T cells which in turn signal B cells, leading to the production of antigen-specific antibodies.
A combination of the above functions means that dendritic cells link innate and adaptive immune responses. Adaptive immunity, while slower to develop compared with innate immunity, is pathogen-specific and greatly decreases pathogen survivability. Furthermore, a memory of the encounter is retained, leading to more rapid and effective responses to subsequent infection by the same pathogen.

Answer 2

The Dendritic cells are responsible for the cooperative working of innate and adaptive immunity.

EXPLANATION:

Dendritic cells are the cells which are multifunctional in nature. They first detect the pathogen entered the host body and also activates the innate response. It also uniquely activates T-cells which produces antigen specific antibody.  It is also known as adaptive immune system. Innate immune system is faster in response as compared to the adaptive immune system.
