That there are senescence-associated decreases in the JAK-STAT signaling transduction cascade has been observed in human lymphocyte lineages. This phenomena, as associated with a decreased JAK- tyrosine phosphorylation of STAT5, is linked to plasma membrane cholesterol content. Therefore, plasma membrane cholesterol content is involved in T cells modulation and proliferation.
Acid sphingomyelinase- mediated ceramide lipid raft mobilization and aggregation of membrane receptors plays a crucial role in this pathobiochemical dynamic leading to multiple disease and comorbidity states in the elderly.
