Group 1 - Immunity
-
B-cells
-
B-cells travel to the site of the injury, upon recognition of an antigen.
Two main types of B-cells that develop when stimulated by an antigen are: B-memory cell and plasma cell.
B-memory cells retain memory of the antigen. The cell reacts by duplication itself many times (clonal selection). They also, recognize antigens that were previously encountered.
The plasma cell is a descendant of B-cell lymphocytes and produces/releases many copies of a protein that is considered now, an antibody. Also, renders the antigen inactive.
Originates from a stem cell in the bone marrow then, resides/matures in lymphoid tissue.

Cellular Involvement
Cytokines
regulatory protein that signals the immune system to send additional phagocytic cells to the site of an infection

Immunopathology
Hypersensitivity
Type IV
Contact dermatitis
mediated, immune response that produces antibodies directly causing damage to tissue cells or recruiting other cells to cause damage, takes two to three days
Type I
-
anaphylactic
(allergy), body reacting to a foreign agent with an exaggerated immune response
Immunodeficiency
immunopathologic condition, compromised or absent immune system involving white blood cells in their products
Autoimmune Diseases
immunopathologic condition, tissue trauma caused by an immune response against tissue constituents’ of one’s own body
Immune Response
Innate
-
immediate response to infection, present always
-
-
Acquired
-
-
-
Does involve memory cells, which may provide lifelong immunity to reinfection to the same infectious agent
-
-
-
Type III
-
immune complex, formation between microorganisms and antibody
Systemic lupus
