B cells
Memory B cells are only active during a specific immune response. They are a type of white blood cell that "remembers" previous pathogens the immune system has encountered and can quickly respond to future infections by producing specific antibodies.
Looking for antigens is part of a specific immune response.

Langerhans cells are the specific cells in the skin that are involved in the immune response. They function as antigen-presenting cells and help to initiate immune reactions by presenting antigens to other immune cells.
adaptive immune response
Looking for antigens is part of a specific immune response.
Naturally acquired active immunity is the type of resistance that is acquired from developing a disease. Naturally acquired active immunity leaves the person immune from developing the disease again in the future.
The innate immune response is the body's first line of defense against pathogens and is non-specific, meaning it does not target specific pathogens. It includes physical barriers like skin and mucous membranes, as well as immune cells like macrophages and natural killer cells. The acquired immune response is more specialized and involves the activation of immune cells such as T and B lymphocytes that target specific pathogens based on memory from past exposures.
The specific immune response is a targeted immune response mounted by the body against a particular pathogen. It involves the activation of lymphocytes (T cells and B cells) and the production of specific antibodies to recognize and neutralize the invading pathogen. This response provides long-lasting immunity against future exposures to the same pathogen.
Memory B cells and memory T cells, which have been previously exposed to a specific pathogen or antigen. These cells can rapidly recognize and respond to the same pathogen upon re-exposure, leading to a faster, stronger, and more targeted immune response. This is the basis for the faster and more effective immune response seen during a secondary immune response.
