Ch1 basic concepts in immunology

Pluripotent Hematopoetic cell
- -located in the bone marrow
- -where all the cellular elements of the blood including the cells of the immune system arise from
Common Myeloid cell

precursor of the macrophages, granulocytes, mast cells, and dendritic cells of the innate immune system and also of megakaryotes
Common Lymphoid cell
- -progenitor cell
- -stem cells that give arise to all lymphocytes. They are derived from pluripotent hematopoietic stem cells
Co stimulatory molecule

Molecules that provide signals that act together with antigen to stimulate T cells
Cells with pathogen associated molecular pattern (PAMPs)
- present in cells of microorganisms
- -helps innate immune system to distinguish self from non self(pathogen)
- -recognized by pattern recognition receptors (PRRs) of the immune system
B lymphocytes (B-cells) and T lymphocytes (T-cells)

Each lymphoid progenitor gives rise to a large number of lymphocytes, each bearing a distinct antigen receptor
Constant and Variable Region

antibody molecules secreted by the b are composed of two regions
During a lymphocyte, one member of each set of gene segments is joined randomly to the others
Periarteriolar lymphoid sheath
Where B cell differentiate into plasma cells
Primary vs. Secondary response
