Clonal Culture Models of T Cell Senescence, 2), as it is now known, normal human T lymphocytes can now be cultured for extended periods allowing for them to be cloned and monoclonal populations to be grown up to usable amounts for experimentation. This still cannot be achieved with other normal immune cells such as B cells or macrophages, wh

Age, T Cell Homeostasis, and T Cell Diversity in Humans,lt life, peripheral homeostatic mechanisms are critical to maintain sizes of T cell subpopulation and diversity of the T cell receptor repertoire. Failure in T cell homeostasis may result in repertoire contraction and increased clonality within the naïve and memory T cell compartments that could neg

The Role of T Regulatory Cells in Immune Senescence,eg are generated either directly from the thymus or via peripheral T cells which acquire regulatory phenotype when activated in the presence of factors such as TGFβ. The relative contribution of these two populations over the life course is unclear. The number of T regulatory cells increases with ag

,Changes of T Cell Receptor (TCR) αβ Repertoire in the Face of Aging and Persistent Infections,his susceptibility is the decrease in output of new naïve TCRαβ T cells from the aging thymus that, coupled to reduced peripheral T cell maintenance later in life, leads to a decline in αβ T lymphocyte numbers with aging (Note that much less is known about maintenance and importance of diversity wit

T-Cell Cycle and Immunosenescence: Role of Aging in the T-Cell Proliferative Behavior and Status Qued cells to rapidly built sufficient numbers of active effector cells, followed by sufficient numbers of memory cells and inhibitory “regulatory” lymphocytes. This huge proliferative activity assures first that the invading pathogens will be effectively neutralized by the lymphocytes in the shortest

Mismatch Repair System and Aging: Microsatellite Instability in Peripheral Blood Cells of the Elderelated reduction in DNA repair capacity of human lymphocytes may contribute to this phenomenon and play a key role in the modification of the immune response observed in the elderly. Because the Mismatch Repair System is the main postreplicative pathway for the correction of replication errors and l

,Generation and Gene Expression of CD28−CD8 T Cells in Human,xpression features of CD28.CD8 T cells. Here, we focus on the role of interleukin-15 (IL-15) in the generation of CD28.CD8 T cells and the identification of unique gene expression in CD28.CD8 T cells by microarray gene expression analysis. These new findings enhance our understanding of the origin a
