Antigen presentation by antigen-presenting cells (APCs) such as dendritic cells is a key part of the specific immune response. APCs process and present antigens to T cells, triggering a targeted immune response against specific pathogens or foreign substances.
Looking for antigens is part of a specific immune response.
The classical pathway is part of the adaptive immune response and is triggered by specific antibodies binding to pathogens. The alternative pathway is part of the innate immune response and is activated by the presence of foreign substances on the surface of pathogens.
Yes, T cells secrete cytokines as part of their immune response.
Phagocytosis is a process where immune cells engulf and digest foreign particles, such as bacteria or viruses, to eliminate them from the body. It is a part of the nonspecific immune response, carried out primarily by macrophages and neutrophils. In the context of specific immunity, phagocytosis plays a role in presenting antigens to lymphocytes to initiate a more targeted immune response.
The classical pathway is part of the innate immune response and is activated by specific molecules on pathogens. The alternative pathway is also part of the innate immune response but is activated by different molecules. Both pathways lead to the activation of the complement system, which helps to eliminate pathogens from the body.
