Recent Advances in T Cell Signaling in Aging
The immune system of mammalian organisms undergoes alterations that may account for an increased susceptibility to certain infections, autoimmune diseases, or malignancies. Well characterized are age related defect in T cell functions and cell mediated immunity. Although it is well established that the functional properties of T cells decrease with age, its biochemical and molecular nature is...

متن کاملCell Signaling
The cardiotoxicity of 5-fluorouracil (FU) was attributed to impurities present in the injected vials. One of these impurities was identified as fluoroacetaldehyde which is metabolised by isolated perfused rabbit hearts into fluoroacetate (FAC), a highly cardiotoxic compound. FAC was also detected in the urine of patients treated with FU. These impurities were found to be degradation products of...
متن کاملOuabain-induced cell signaling.
When endogenous ouabain was first isolated from human plasma in 1991, many expressed doubts that such a compound could be endogenous to humans because of its unusual structure, its unknown synthesis, and its unidentified site of origin. Furthermore, the relevance of human ouabain was questioned because of its apparently low (< or =nmol/L) circulating concentration. Since then, much progress has...

The plant hormone abscisic acid (ABA) regulates the aperture of the stomatal pore. The recent identification of new intermediates involved in ABA signaling suggests that this complex pathway is organized as a module-based network.
