Tissue-resident memory T cells in the era of (Neo) adjuvant melanoma management.

Tissue-resident memory T (T) cells have emerged as key players in the immune control of melanoma. These specialized cells are identified by expression of tissue retention markers such as CD69, CD103 and CD49a with downregulation of egress molecules such as Sphingosine-1-Phosphate Receptor-1 (S1PR1) and the lymphoid homing receptor, CD62L. T have been shown to be integral in controlling infections such as herpes simplex virus (HSV), lymphocytic choriomeningitis virus (LCMV) and influenza.

The TOMM40 '523' polymorphism in disease risk and age of symptom onset in two independent cohorts of Parkinson's disease.

Abnormal mitochondrial function is a key process in the pathogenesis of Parkinson's disease (PD). The central pore-forming protein TOM40 of the mitochondria is encoded by the translocase of outer mitochondrial membrane 40 homologue gene (TOMM40). The highly variant '523' poly-T repeat is associated with age-related cognitive decline and age of onset in Alzheimer's disease, but whether it plays a role in modifying the risk or clinical course of PD it yet to be elucidated.
