self antigens that resemble foreign antigens cause T cells to misidentify natural cells and mount an immune attack (theory) |
cross-antigen theory |
|
|
(theory) Infection, trauma, drugs, and radiation alter natural cells . Consequently they no longer resemble self-antigens |
tissue-inury theory |
|
|
viruses alter T-Cell receptors that are used to differentiate from self to non self (theory) |
viral mutation theory |
|
|
some cells, like those of the thyroid, brain, and lens of eye are seperated from lymphocytes during fetal development . When these cells enter circulation later because of trauma or infection, T cells do not recognize them as "self" (theory) |
seqeustered antigen theory |
|
|
reduced numbers of suppressor cells or a shortened lifespan because of aging and atrophy of the thymus gland alter immunoregulation (theory) |
Diminished T-suppressor theory |
|
|
Genetic coding for antibody production is altered , which explains the familial pattern to some autoimmune disorders (theory ) |
Genetic instruction theory |
