Background of CD3 antibody
The antigen receptor on human T lymphocytes consists of two variable immunoglobulin-like glycoproteins, alpha and beta or TCR-gama and delta, which occur in association (noncovalently) with three invariable T3 membrane proteins (CD3-gamma, CD3-delta and CD3 epsilon). In humans two of these proteins, T3-gamma and T3-delta, are glycoproteins of relative molecular mass (Mr) 25,000 (25K) and 20,000 (20K), respectively, while the third, T3-epsilon, is a 20K non-glycosylated protein. A keystone of the antigen-specific immune response is the T-cell receptor (TCR)/CD3 complex. CD3 antigen has gamma, delta, epsilon, and theta chains. The CD3 complex consist of various chains (alfa, beta, gamma, theta, epsilon and delta) mediates signal transduction in T cell receptor cells. The TCR/CD3 complex of T-lymphocytes consists of either a TCR alpha/beta or TCR gamma/delta heterodimer co-expressed at the cell surface with the invariant subunits of CD3 labeled gamma, delta, epsilon, zeta, and eta. The infection of CD3 positive cells with HTLV led to a decrease in CD3 antigen expression. The onset of this phenomenon coincided with a decrease of CD3γ followed by the subsequent progressive reduction in CD3δ, then CD3ε and CD3ζ mRNA. This decrease in CD3 expression is a direct result of epigenetic control regulation of CD3 genes as determined by DNAse I hyper sensitivity assay (DHS) (1).
Antibodies to CD3 epsilon chain is a glycosylated protein of 290 amino acids with a single trans-membrane spanning domain residing between 127-149 with an apparent MW of 20 kDa. The epsilon chain of CD3 complex is non-glycosylated and is involved in rapid turnover of phosphotidylserine and accumulation of intracellular Ca after antigen receptor activation on T cell. The CD3 epsilon gene consist of nine exons and three mini exons of 21, 15 and 18 bases, the epsilon gene is transcribed form weak, tissue non-specific TATA less promoter (2).
The CD3E-selective (CD3 epsilon chain) antibodies were generated against peptide form unique region of the CD3 gene that is not present in other CD3 antigen chains or other cellular proteins. The antigenic sequence was common in several species but distinct from other CD antigens.
