Aging, longevity, and diet: historical remarks on calorie intake reduction.

abstract：:Acquisition of immunologic self-tolerance by clonal deletion in the thymus is concluded to be a critical process in immune aging and is found to be transiently protected from genetic instability by means of a feedback surveillance which functions at the expense of chronic thymic involution. In the immune control of ma...
