IMMUNOLOGY

Detailed explanation-1: -During the immune response, mediators such as cytokines are also produced. The adaptive immunity is divided into two types: antibody mediated immunity and cell immunity (mediated by cytotoxic T cells) (1–4). The immune mechanism produced may kill or destroy germs and thus, giving us protection/immunity.

Detailed explanation-2: -Successful innate immune protection is achieved through two steps. First, identifying targets, such as pathogens and abnormal tissues and cells. Second, by orchestrating humoral and cell effectors to neutralize and eliminate the identified targets.

Detailed explanation-3: -Natural killer (NK) cells: These rapid-response cells attack viruses and may also be aggressive in attacking cancerous and pre-cancerous cells. The acquired immune system-also called adaptive immunity-is more sophisticated and takes longer to develop a plan of attack.
