Leader in Biomolecular Solutions for Life Science ITGAE Rabbit pAb Catalog No.: A9934 Basic Information Background Catalog No. Integrins are heterodimeric integral membrane proteins composed of an alpha chain A9934 and a beta chain. This gene encodes an I-domain-containing alpha integrin that undergoes post-translational cleavage in the extracellular domain, yielding disulfide- Observed MW linked heavy and light chains. In combination with the beta 7 integrin, this protein forms 110kDa the E-cadherin binding integrin known as the human mucosal lymphocyte-1 antigen. This protein is preferentially expressed in human intestinal intraepithelial lymphocytes Calculated MW (IEL), and in addition to a role in adhesion, it may serve as an accessory molecule for IEL 130kDa activation.

The CD CD8 CD8 nomenclature was developed and is maintained through the HLDA (Human Leukocyte Differentiation Antigens) workshop started in 1982. CD45R/B220 CD19 CD19 The goal is to provide standardization of monoclonal antibodies to B Cell CD20 CD22 (B cell activation marker) human antigens across laboratories. To characterize or “workshop” the antibodies, multiple laboratories carry out blind analyses of antibodies. These results independently validate antibody specificity. CD11c CD11c Dendritic Cell CD123 CD123 While the CD nomenclature has been developed for use with human antigens, it is applied to corresponding mouse antigens as well as antigens from other species. However, the mouse and other species NK Cell CD56 CD335 (NKp46) antibodies are not tested by HLDA. Human CD markers were reviewed by the HLDA. New CD markers Stem Cell/ CD34 CD34 were established at the HLDA9 meeting held in Barcelona in 2010.

Role of ITGAE in the Development of Autoimmune Diabetes in Non-Obese Diabetic Mice

Given that ITGAE (CD103) recognizes an islet- " autoimmune restricted ligand (E-cadherin), we postulated that its expression is required for initiation of " immune system disease. We herein use a mouse model of autoimmune diabetes (NOD/ShiLt mice) to test this " mouse C hypothesis. We demonstrate that ITGAE is expressed by a discrete subset of CD8 T cells that infiltrate pancreatic islets before the development of diabetes. Moreover, we demonstrate that development of diabetes in Itgae-deficient NOD mice is significantly delayed at early Journal of Endocrinology but not late time points, indicating that ITGAE is preferentially involved in early diabetes development. To rule out a potential contribution by closely linked loci to this delay, we treated WT NOD mice beginning at 2 weeks of age through 5 weeks of age with a depleting anti-ITGAE mAb and found a decreased incidence of diabetes following anti-ITGAE mAb treatment compared with mice that received isotype control mAbs or non-depleting mAbs to ITGAE.

CD103 / ITGAE Antibody
FOR RESEARCH USE ONLY! 02/21 CD103 / ITGAE Antibody CATALOG NO.: A2300-50 (50 µg) A2300-100 (100 µg) BACKGROUND DESCRIPTION: ITGAE, also known as CD103, is an integrin that pairs with the beta 7 integrin to form the human mucosal lymphocyte-1 antigen. ITGAE is preferentially expressed in human intestinal intraepithelial lymphocytes (IEL). It has a role in adhesion and may serve as an accessory molecule for IEL activation. ITGAE has been associated with diseases such as hairy cell leukemia and splenic marginal zone lymphoma. The presence of cytotoxic T cells positive for CD103 expression has been linked to prolonged survival in several malignancies, including gastric cancer, and is currently being explored as a prognostic biomarker as well as a potential therapeutic target.

Here, we proﬁle 176,447 cells from 10 NPC tumour-blood pairs, using single-cell transcriptome coupled with T cell receptor sequencing. Our analyses reveal 53 cell subtypes, including tumour-inﬁltrating CD8+ T, regulatory T (Treg), and dendritic cells (DCs), as well as malignant cells with different Epstein-Barr virus infection status. Trajectory analyses reveal exhausted CD8+ T and immune-suppressive TNFRSF4+ Treg cells in tumours might derive from peripheral CX3CR1+CD8+ T and naïve Treg cells, respectively. Moreover, we identify immune- regulatory and tolerogenic LAMP3+ DCs. Noteworthily, we observe intensive inter-cell interactions among LAMP3+ DCs, Treg, exhausted CD8+ T, and malignant cells, suggesting potential cross-talks to foster an immune-suppressive niche for the TME. Collectively, our study uncovers the heterogeneity and interacting molecules of the TME in NPC at single-cell resolution, which provide insights into the mechanisms underlying NPC progression and the development of precise therapies for NPC.
