產(chǎn)品介紹 | 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對T細胞的活化、增殖起著重要的負調(diào)控作用,BTLA相應配體為TNFR超家族中的皰疹病毒入侵介質(zhì)(HVEM), 其表達于包括T細胞在內(nèi)的多種免疫細胞表面。 有學者將他定為CD28的超級族成員,B、T淋巴細胞衰減子-CD272主要用于細胞信號傳導方面的研究。 近來國外學者對BTLA用于抑制腫瘤方面的研究也有了新的進展,認為B、T淋巴細胞衰減子對腫瘤的生長有抑制作用,探索新的腫瘤免疫治療有了新的途徑, 封閉此途徑有可能成為腫瘤免疫治療的新靶點。 |

Primary Antibody:Rabbit Anti- CD272 antibody(bs-0624R), Dilution: 1μg in 100 μL 1X PBS containing 0.5% BSA; Isotype Control Antibody: Rabbit IgG(orange) ,used under the same conditions ); Secondary Antibody: Goat anti-rabbit IgG-PE(white blue), Dilution: 1:200 in 1 X PBS containing 0.5% BSA. 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. |
