As an hypothetico-deduction, Dr. Guerra proposes that the Recombination Activating Gene-RAG System is a Potential Candidate in Age Associated Morbidity.
In conjunction with a neutral sphingomyelinase and the subsequent synthesis of diacylglycerol thence promoting activation of a PKC-Zeta, T cell receptor translocation and activation are obtained.
Prior RAG mediated recombination events in CNS-resident lymphocytes, associated microglia and neurons can lead to recombination event epigenomic ontologies that either promote or curtail a resident hyperimmune response leading to classical neurodegenerative diseases of the elderly.
