Do multi-layered epigenetic mechanisms contribute to transcriptional memory in T lymphocytes?
Current global health challenges in areas such as tuberculosis and influenza demand not only more effective and safer vaccines, but also vaccines for a wider range of health priorities, including HIV, cancer, and emerging pathogens such as Ebola. Understanding the multi-layered epigenetic mechanisms that underpin the rapid recall responses of memory T cells following reactivation is a critical component of this development pathway.
The schizophrenia-specific reduction in complex I subunits in the prefrontal cortex is consistent with one of schizophrenia's most prominent deficits, namely, hypofrontality, thus further supporting the hypothesis of mitochondrial dysfunction in this disorder. The abnormal, bidirectional expression of complex I in various brain regions, rather than in a circumscribed area, supports the idea of impaired cerebral circuitry in schizophrenia.
