Besides 2-methoxy-17beta-estradiol, cell cycle arrest via chromatin deacetylation  can mitigate cell proliferation by decreasing global transcription while promoting the expression of tumor suppressor genes like p16INK4a while DNA Damage Repair (DDR) from pro-inflammatory cytokine production from senescent cells and Th1 lymphocytes can  inhibit commitment to mitosis and cytokinesis by ge...

Cell fate from Either ageing associated senescence to programmed cell death OR cell proliferation is finely tuned to the splice variant  expression of Cell Cycle dependent kinase inhibitors and the relative production of pro-inflammatory cytokines under the synchrony of DNA Damage Repair (DDR), telomerase expression decline, and the protective role of the Senescence Associated Secretory Pheno...

The Src-family kinase Lck regulates T-cell development, activation, proliferation, and immune synapse dynamics. These are the initiation phases of TCR  signaling. Upon antigen presentation via the APC- TCR immune synapse, Lck phosphorylates tyrosine residues within the immunoreceptor tyrosine-based activation motifs (ITAMs) of the TCR-associated CD3 membrane protein domains.  Phosphoryla...

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 sphi...

Chromatin instability leads to alterations in gene expression that re-directs cellular senescence by corruption of chemokine and cytokine signalling resulting in epithelial to mesenchymal transitions and the potential for metastatic cancer in the elderly . As lymphocyte lineage's age these underlying pathobiochemical events are potentiated by hypo and hyper immune responses thus generating a downw...

ILC3 can contribute to the progression and aggravation of IBD's while both IL-22 and IL-17, along with IFN-γ, are overexpressed by the dysregulation of NCR− ILC3 or NCR+ ILC3 function NCR (natural cytotoxicity receptors), are  type 1 transmembrane proteins of the immunoglobulin superfamily. Upon stimulation, NCR's mediate NK killing and release of IFNγ. They bind viral ligands such as hemaggl...

Omega-Three VLCPUFA's as asymmetrically distributed in membrane glycerolphospholipids mediate vesiculation and permeability of endothelia to circulating lymphocytes and leukocytes thus coupling folic acid, Vitamin B12 and epigenetic modification of chromatin to ultimately link bioenergetics with cytotoxicity and inflammation. This regulated system involves the neuroimmunoepigenome and the senescen...

Pro-inflammatory gene transcription is tanked when demethylation is inhibited but cytotoxicity of  virally infected or cancer cells by NK’s (where demethylation is inhibited) remains intact. References J. Biol. Chem. 2018;293:2422-2437 J. of Biol. Chem. 2016. 291, 23756-23768

Dr. Guerra discusses some of the complexity of both the epigenetic mechanisms and cellular responses associated with immunomodulatory failure  in the aging human.

Dr. Guerra continues a dialectical accounting of the biochemical and cellular events leading to the terminal outcome of aging. Topic today is the reintroduction of Natural Killer Cells and the epigenetic mechanisms that orchestrate unique gene expression.  References Anal Cell Pathol (Amst). 2018; 2018: 787.1814.
