IMMUNOLOGY

Detailed explanation-1: -Dendritic cells are immune cells that process antigen material; they are present in the skin (Langerhans cells) and the lining of the nose, lungs, stomach, and intestines. Sometimes a dendritic cell presents on the surface of other cells to induce an immune response, thus functioning as an antigen-presenting cell .

Detailed explanation-2: -Indeed, dendritic cells are the only antigen-presenting cells that induce the activation of resting T cells, both in vitro and in vivo. Thus, dendritic cells initiate adaptive immune responses and determine tolerance.

Detailed explanation-3: -Thus, pentraxins recognize and bind viral antigens to initiate the humoral innate immune response.
