Homeostatic T Cell Proliferation
Through positive and negative selection, the thymus allows a small fraction of immature CD4 ϩ 8 ϩ double positive thymocytes to differentiate into mature CD4 ϩ 8 Ϫ or CD4 Ϫ 8 ϩ single positive cells; these cells are released into the periphery to establish the mature T cell pool. Positive selection rescues thymocytes that express TCR with low affinity for peptides bound to MHC molecules express...
متن کاملHomeostatic T Cell Proliferation after Islet Transplantation
Pancreatic islet transplantation in patients with type 1 diabetes mellitus is performed under immunosuppression to avoid alloreactive T cell responses and to control the reactivation of autoreactive memory T cells. However, lymphopenia associated with immunosuppression and T cell depletion can induce a paradoxical expansion of lymphocyte subsets under the influence of homeostatic proliferation....
متن کاملMir-55 inhibition can reduce cell proliferation and induce apoptosis in Jurkat (Acute T cell Leukemia) cell line
Background MicroRNAs are small and non-coding RNA molecules with approximately 22 nt in length that cause inhibition of translation or degradation of mRNA. MiR-155 is a kind of molecule with different functions, such as its role in proliferation, apoptosis, inflammation, differentiation, and immunity. One of its best known functions is apoptosis that affects on caspase-3 activity. The main aim...
متن کاملTargeting Homeostatic T Cell Proliferation to Control Beta-Cell Autoimmunity
Immunomodulation of the autoreactive T cell response is considered a major strategy to control beta-cell autoimmunity, both in the natural history of type 1 diabetes and in islet transplantation, which can be affected by autoimmunity recurrence. So far, these strategies have had modest results, prompting efforts to define novel cellular and molecular targets to control autoreactive T cell expan...
متن کاملFibroblast and T cells conditioned media induce maturation dendritic cell and promote T helper immune response
Dendritic cells (DCs) induce pathogen-specific T cell responses. We comprehensively studied the effects of addition of maturation stimulus, fibroblasts (fibroblast conditioned medium), PHA activated T cells (T cell conditioned medium), and mixture of fibroblast & PHA activated T cells (FCM-TCCM) conditioned media on maturation of DCs. Monocytes were cultured with GM-CSF and IL-4 for five days. ...
