  • Immunofluorescence staining of Hela cells with CSB-PA004894LA01HU at 1:166, counter-stained with DAPI. The cells were fixed in 4% formaldehyde, permeabilized using 0.2% Triton X-100 and blocked in 10% normal Goat Serum. The cells were then incubated with the antibody overnight at 4°C. The secondary antibody was Alexa Fluor 488-congugated AffiniPure Goat Anti-Rabbit IgG(H+L).

Target Background

CD2 interacts with lymphocyte function-associated antigen CD58 (LFA-3) and CD48/BCM1 to mediate adhesion between T-cells and other cell types. CD2 is implicated in the triggering of T-cells, the cytoplasmic domain is implicated in the signaling function.
Gene References into Functions
  1. A new prognostic model for HR-/HER2+ breast cancer based on the expression of MMP11 and CD2 was developed and the distant metastasis-free survival for patients in the high-risk group according to our model was significantly lower than that for those in the low-risk group. PMID: 28409241
  2. These results reveal an unexpected redundancy in the human NK cell response to human cytomegalovirus and suggest that CD2 provides "signal 2" in antibody-driven adaptive NK cell responses. PMID: 27117418
  3. Establish CD2 as a new susceptibility factor for systemic sclerosis in a European Caucasian population. PMID: 27385538
  4. the fundamental mechanism of glycosylation of human CD2 is to promote CD2-CD58 binding by conformational adjustment of CD2 PMID: 25984915
  5. CD58/CD2 is the primary costimulatory pathway in human CD28-CD8+ T cells. PMID: 26041540
  6. Both the mRNA expression levels and protein expression levels of HSP27 were increased in astrocytes from POAG patients compared with those from normal control, suggesting that mutation in CD2 might pose a risk for POAG in Chinese population. PMID: 24597656
  7. Although sMCs displayed immunoreactivity for one of the neoplastic antigens in the majority of SM patients, the aberrant CD2 and/or CD25 expression on sMCs is not as indicative of SM as the BMMC immunophenotype. PMID: 25402852
  8. ERGdel may be a pure surrogate of CD2-positivity--which has been suggested to be a good prognositc marker in childhood ALL PMID: 24072102
  9. Altogether, these results show that a high CD2 expression level is a hallmark of latently infected resting memory CD4(+) T cells in vivo. PMID: 23760244
  10. Aberrant CD2 expression appears to further determine a shorter progression free survival PMID: 22634534
  11. CD2-CD58/48 receptor-ligand interaction promotes and is required for nanotube formation in human natural killer cells. PMID: 23112830
  12. CD2 expression does not contribute to improve the diagnosis of systemic mastocytosis when compared with aberrant CD25 expression alone. PMID: 22222639
  13. CD2-mediated priming of resting natural killer (NK) cells is unaffected by their degree of functional maturation. PMID: 22084431
  14. CD2 signals more strongly to S6-ribosomal protein, whereas CD28 costimulation specifically induces signaling necessary for proper NF-kappaB activation. PMID: 22013130
  15. When isolated from multiple sclerosis patients, both nonmature and effector subsets of memory CD127(low) regulatory T cells exhibit kinetically distinct defects in suppression that are evident with CD2 pathway costimulation. PMID: 21300823
  16. analysis of the importance of homotypic NK-to-NK cell cross-talk through 2B4/CD48 and CD2/CD58 pairs and further present their differential and overlapping roles in human NK cells PMID: 20813844
  17. PTEN expression was up-regulated on RNA and protein level in freshly isolated human CD4(+) T cells following stimulation with CD28 or CD2. PMID: 11932928

  19. Structural and functional studies of the extracellular domains of CD2 and CD58 and their complex. Review. PMID: 12369898
  20. CD2BP2 is the ligand of the membrane-proximal proline-rich tandem repeat of CD2 in detergent-soluble membrane compartments, but is replaced by Fyn SH3 after CD2 is translocated into lipid rafts upon CD2 ectodomain clustering. PMID: 12426371

  27. We use this analysis to determine that the 2D Kd for CD2-CD58 is 5.4-7.6 molecules/microm2. 2D Kd analysis provides a general and quantitative measure of the mechanisms regulating cell-cell adhesion. PMID: 17085486
  28. T cell activation causes the CD58-bound CD2 to be recognized and immobilized at sites of cell-cell contact, thereby strengthening T cell-APC adhesion PMID: 17168569
  29. results showed that the expression of CD2 significantly increased with the severity of chronic HBV infection, which suggested that CD2 might contribute to the hepatocyte damage in chronic HBV infection PMID: 18318997
  30. Data suggest that detection of CD2 or CD13 expression in chronic lymphocytic leukemia (CLL) suggests familial CLL, and that CD38 expression does not carry the negative prognosis observed in sporadic CLL. PMID: 18431797
  31. the synergistic synthesis of IL-8 occurs when lymphocytes are stimulated through the CD2 pathway by CD58 on HT-29 cells, resulting in TNF-alpha release that, in turn, augments IL-8 synthesis and CD58 expression by the HT-29 cells PMID: 19109405
