| 产品介绍 | B and T lymphocyte attenuator (BTLA), an immunoglobulin domain-containing glycoprotein with two immunoreceptor tyrosine-based inhibitory motifs. BTLA is not expressed by naive T cells, but it is induced during activation and remains expressed on T helper type 1 (T(H)1) but not T(H)2 cells. Crosslinking BTLA with antigen receptors induces its tyrosine phosphorylation and association with the Src homology domain 2 (SH2)-containing protein tyrosine phosphatases SHP-1 and SHP-2, and attenuates production of interleukin 2 (IL-2). BTLA-deficient T cells show increased proliferation, and BTLA-deficient mice have increased specific antibody responses and enhanced sensitivity to experimental autoimmune encephalomyelitis. B7x, a peripheral homolog of B7, is a ligand of BTLA. Thus, BTLA is a third inhibitory receptor on T lymphocytes with similarities to cytotoxic T lymphocyte-associated antigen 4 (CTLA-4) and programmed death 1 (PD-1). Function: Lymphocyte inhibitory receptor which inhibits lymphocytes during immune response. Subunit: Interacts with tyrosine phosphatases PTPN6/SHP-1 and PTPN11/SHP-2. Interacts with TNFRSF14/HVEM. Subcellular Location: Membrane; Single-pass type I membrane protein (Potential). Post-translational modifications: Phosphorylated on Tyr residues by TNFRSF14 and by antigen receptors cross-linking, both inducing association with PTPN6 and PTPN11. N-glycosylated. Similarity: Contains 1 Ig-like V-type (immunoglobulin-like) domain.

BTLA对T细胞的活化、增殖起着重要的负调控作用，BTLA相应配体为TNFR超家族中的疱疹病毒入侵介质（HVEM）, 其表达于包括T细胞在内的多种免疫细胞表面。 有学者将他定为CD28的超级族成员，B、T淋巴细胞衰减子-CD272主要用于细胞信号传导方面的研究。 近来国外学者对BTLA用于抑制肿瘤方面的研究也有了新的进展，认为B、T淋巴细胞衰减子对肿瘤的生长有抑制作用，探索新的肿瘤免疫治疗有了新的途径， 封闭此途径有可能成为肿瘤免疫治疗的新靶点。 |

Protocol The cells were fixed with 2% paraformaldehyde (10 min) . Primary antibody (bs-0624R, 1μg /1x10^6 cells) were incubated for 30 min on the ice, followed by 1 X PBS containing 0.5% BSA + 1 0% goat serum (15 min) to block non-specific protein-protein interactions. Then the Goat Anti-rabbit IgG/PE antibody was added into the blocking buffer mentioned above to react with the primary antibody at 1/200 dilution for 30 min on ice. Acquisition of 20,000 events was performed. |
