Glucocorticoids dysregulate 20% of the human genome. Mabs anti-CD20 do not modify the genome, are safer and eficient

Authors: Giuliani R A

Abstract: Glucocorticoids (GCs) up or down-regulates the expression of thousands of genes by binding to Glucocorticoid Receptors (GRs). By alternative splicing of its terminal exons 9α or 9β in the primary transcript and readings through 8 different Start Codons, the GR gene develops16 isoforms. Each one of them admits 16 dimeric combinations and 256 homodimeric versions of GR. Cortisol travels in plasma tied to Cortisol Binding Globulin (CBG), which modulates its distribution and access to every cell and tissue of the body. Its cytosol biodisponibility is determined by 11β-HSD types 1 and 2 enzymes. The panel and final concentration of GR monomers and dimers changes according to the differentiation programme of each cell. The infusión of semisynthetic GCs totally disorganyze the delicate balance induced by the hypothalamus on almost 20% of the Human Genome. Because of it, chronic infusión of semisynthetic GCs results in more damage than benefit. Antibodies like anti-CD20, anti-TNF or Anti-BLyS, react against specific targets on B or T Cells, are more effective and do not modify the evenly expression of thousands of Cortisol’s dependent genes.
