Diabetes Milletes Immunopathaogenesis
Dr. Ryad KhanfarBy : Abdelrahman Al-daqqa
β-Cell-Specific T Cells Are Present in Healthy Individuals but Do Not Attack β Cells
They can then be stimulated by the corresponding autoantigen when it is adequately presented to them in the context of MHC molecules.
Autoantigens : insulin insulin (or proinsulin), GAD, IA.2, a tyrosine phosphatase, and IGRP.
They induce the production of T cells or autoantibodies in NOD mice or diabetic patients.
Regularity T-cells slow down
Genetics : AIRE , HlA-DR3/4Environmental : i.e ; viral
Are immunological tests useful?
The autoantibodiesautoantibodies response to islet cell antigens predict the risk of developing IDDM.
The titre of ICAtitre of ICA also is important (if ICA high-> 500 times more likely to develop IDDM) .
However , no available immunological intervention for tom prevent B-cell destruction , so these tests are not effectivenot effective until discovering a new txt !
