Cells and Organs Of The Immune System Flashcards
Two types of T helper cells:
TH1 cells help the CD8+pre-cytotoxic cells.
TH2 cells help B cells
Two major lineages:
Myeloid precursor and lymphoid precursor
Type of the immune system responsible for the maturation of antigen-reactive cells.
Primary response
Type of immune system responsible for antigen contact and response
Secondary response
Two main type of tissue that disposes worn-out bloodness
Red pulp
Two main type of tissue that contains the lymphoid tissue
White pulp
Large white cells that can engulf and digest marauding microorganism and other antigenic particles. Some have the ability to present antigen to lymphocytes
Phagocytes
Important phagocytes
Monocyte and macrophage
Other antigen-presenting cells;
B cells, macrophage, type 1 & 2 dendritic cells
Irregularly shoed wbc. Have long threadlike tentacles that enmesh lymphocytes and antigens. Can be found in spleen.
Dendritic cells
These are dendritic cells that travel in the skin, picking up antigen and transporting it to lymph nodes. Found in pancreas
Langerhans cells
They play a key role in acute inflammatory response
Neutrophils
It is a noncirculating counterpart of the basophil. Located in the lungs, skin, tongue, and linings of the nose and intestinal tract. Responsible for the symptoms of allergy.
Mast cell
F: SRBC receptor, t cell adhesion/ activation
CD2
Signal transduction
CD3
Co-recognition of MHC class 2 with TCR, primary receptor of HIV retrovirus
CD4
Involved in signaling through TCR and BCR
CD5
Involved in T cell proliferation, cell adhesion
CD6
