A comparable pattern of systemic CD4 T cell activation was observed in patients with CIS and MS, although patients with MS had a somewhat higher percentage of CD4 T cells in blood expressing CD26, and more CD4 T cells in CSF expressing CD71, than did CIS patients.
Several steps in the gene expression process may be modulated, including the transcription, RNA splicing, translation, and post-translational modification of a protein.n genetics, gene expression is the most fundamental level at which the genotype gives rise to the phenotype. The genetic code stored in DNA is interpreted by gene expression, and the properties of the expression give rise to the organism's phenotype.
Diagram showing at which stages in the DNA-mRNA-protein pathway expression can be controlled. Gene expression is the process by which the heritable information in a gene, the sequence of DNA base pairs, is made into a functional gene product, such as protein or RNA. The basic idea is that DNA is transcribed into RNA, which is then translated into proteins. Proteins make many of the structures and all the enzymes in a cell or organism. Several steps in the gene expression process may be modulated (tuned).
