What is Rheumatology?
T he study of rheumatism, arthritis, and other disorders of the joints, muscles, and ligaments.
Innate Immune System
- External body membranes
- Inflammation (antimicrobial proteins, phagocytes and other cells)
- Surface barriers and internal barriers
Adaptive Defense Immune System
- Humoral (B cells)
- Cellul ar (T cells)
Neutrophils (polymorphonuclear leukocytes /PMN's
The most abundant population of circulating WBCs, ~50%+ of WBC's. Found in the bloodstream,
migrate into sites of infection within a matter of minutes. Mediate the earliest phase of
inflammatory reactions.
Monocytes
Closely related to neutrophils, in the bloodstream. 5-10% of WBC's. When monocytes leave the
bloodstream and enter the tissues, they change shape and size and become macrophage.
Macrophages
Antigen-presenting cell (APC) involved in the detection, phagocytosis, and destruction of
pathogens.
Dendritic Cells
Antigen-presenting cells (APCs) for activating naïve T cells. They have long membranous
projections and phagocytic capabilities. They display microbial antigens to T lymphocytes.
Eosinophils
,Granulocytes that express cytoplasmic granules containing enzymes that are harmful to the cell
walls of parasites. 1-3% WBC's. Responsible for participating in immediate allergic reactions,
modulating inflammatory responses.
Basophils
Granulocytes present in blood stream, <1% of WBC's. Generally involved with allergies.
B-Cells
Involved in Humoral response. Produce antibodies/ immunoglobulins (Ig). Once exposed to an
antigen, mature into plasma and memory B cells. Also act as APC's.
CD8 T Cells (TC)
Involved in Cell-Mediated response. Target virally infected or altered "self" cells.
CD4 T Cells (TH)
Involved in Cell-Mediated response. When exposed to an antigen, activate B cells and TC.
Regulator T Cells (Treg)
Mediates the immune response by inhibiting B and T cells.
Natural Killer Cells (NK)
Present in low numbers, large granular lymphocytes that target virally infected and altered
"self" cells without surface markers typical of B or T Cells.
Inflammation
- Body's response to tissue damage from injury or infection
- Can be characterized by increased temperature, redness, swelling & pain
- Caused by microbial
pathogens, injury (ie. Cuts, burns, sunburn), autoantigens, chemicals & allergies
- Cell damage > vessel dilation > increased blood flow > swelling/redness/warmth > migration of
innate and adaptive immune system components to affected site > cytokine release
Cytokines
Any of a number of substances, (i.e. interferon (ex: INF), interleukin (ex: IL-1), and growth
factors (ex: TNF) which are secreted by certain cells of the immune system influence other cells.
Major Histocompatibility Complex (MHC)
, - Different gene controls that help body identify self and non self
- Will look for MH molecules that are supposed to be there, other MH that will determine that
these cells are not supposed to be here
- Genes control: self/non-self & cell-surface recognition systems required for appropriate
lymphocyte responses (class I & II) & synthesis of certain complement components & stress-
related proteins (class III)
Complement Pathway
- Refers to a 20+ large regulatory proteins that circulate in plasma in an inactive form
- When activated, typically activates phagocytosis to clear out antigen that is not supposed to
be there -> cascade of reactions
- Non specific for everyone
- Can form Membrane Attack Complex (MAC) perform immune cytolysis - to pop cells that
aren't supposed to be there
Adaptive Immunity
- B cells, which express immunoglobulin-like (IL) cell surface receptors, may undergo negative
selection (ie, B cells are eliminated or silenced (Anergy) to avoid binding to self-antigens,
allowing self-tolerance
- Can undergo positive selection for binding to some antigens
- When exposed to antigens under appropriate conditions (i.e. following immunization or
infection)> 1. B cells expand in number and undergo further immunoglobulin gene mutation to
select immunoglobulins that bind more tightly or avidly to the target. This process is termed
affinity maturation. B cell clones> plasma cell and memory B Cell formation occurs, if something
occurs again.
Humoral Immunity (B Cells)
Depends on:
- Ability of B lymphocytes to recognize specific antigens &
- Their ability to initiate responses that protect the body against foreign agents
- Each kind carry specific antibody on membrane
- Responses of B cells can be influenced by certain T-cell
Antibodies
- Encoded by immunoglobulin genes involving combinations of heavy-chain constant region
genes splicing with heavy-chain variable region genes and light-chain constant region genes
splicing with light chain variable region genes
- Transcription & assembly of the heavy and light chains occurs within B cells and plasma cells
