“Alpha Gam is always reaching to a higher standard and the technology we offer our chapter leaders is no exception,” said Alpha Gamma Delta Executive Director, Katie Jolley Abernathy. With sisterhood at the forefront, Alpha Gam’s 199 chapters and over 189,000 members strive to attain a higher standard, thereby improving their lives, the lives of those around them, and the communities in which they live. All parties are devoted to delivering Alpha Gamma Delta’s members the best member experience and providing the technology infrastructure needed to be successful now and in the future.Īlpha Gamma Delta, an international women’s organization, is committed to providing opportunities for personal development, service to others, and a space for members to forge their own paths. Alpha Gamma Delta has also partnered with ChapterSpot, an industry-leading CRM and member management tool built on the Salesforce platform. Billhighway’s full-service solution maximizes chapter success with proven technology that automates chapter workflows and streamlines financial processes.

The potential of γδ T cells for pan-population immunotherapy will be evaluated in upcoming clinical trials using different subsets of γδ T cells or specific γδ TCRs.Billhighway, an industry-leading financial management platform dedicated to chapter-based organizations, is thrilled to announce a new partnership with Alpha Gamma Delta (Alpha Gam). Past clinical trials, which focused on Vγ9/Vδ2+ T cells expanded using phosphorylated metabolites, showed an overall good safety profile but the clinical efficacy was generally underwhelming. Γδ T cells are capable of recognising and lysing diverse cancers in an MHC-unrestricted manner, highlighting their potential for pan-population immunotherapy, in contrast to MHC-restricted αβ T-cell mediated immunotherapy. human cytomegalovirus) have been shown to drive clonal expansion of peripheral γδ T cells bearing person-specific TCRs, indicating the adaptive nature of γδ T cell-mediated immune response. In particular, human Vγ9/Vδ2+ T cells are capable of serving as professional antigen presenting cells.Ĭertain infections (e.g. Γδ T cells display broad functional plasticity following recognition of infected/transformed cells by production of cytokines (IFN-γ, TNF-α, IL-17) and chemokines (RANTES, IP-10, lymphotactin), cytolysis of infected or transformed target cells (perforin, granzymes, TRAIL), and interaction with other cells including epithelial cells, monocytes, dendritic cells, neutrophils, and B cells. Finally, γδ TCRs have been shown to recognise lipid antigens presented by CD1 molecules, in particular CD1d. Stress surveillance performed by γδ T cells is thought to depend not only on their TCRs but also on co-stimulatory signals from, for instance, NK-type receptors. Some γδ T cells also recognise markers of cellular stress, resulting from infection or tumorigenesis. Due to metabolic dysregulation IPP is often accumulated by cancer cells. Human Vγ9/Vδ2+T cells show TCR-dependent activation by certain phosphorylated metabolites such as microbial HMB-PP or eukaryotic isoprenoid precursor IPP. A small proportion of murine γδ T cells (<1%) bind the MHC-I-related proteins T10 and T22 that are expressed by highly activated cells. The antigens recognised by most γδ T cells are still unknown. The majority of γδ T cells are activated in an MHC-independent manner, in striking contrast to MHC-restricted αβ T cells. Recognition of target cells by γδ T cells In general, γδ T cells are enriched in epithelial and mucosal tissues where they are thought to serve as the first line of defense against pathogenic challenge. For instance, human peripheral blood γδ T cells are largely Vγ9/Vδ2+, and murine skin γδ T cells, so-called dendritic epidermal T cells (DETCs), are largely Vγ5/Vδ1+. Γδ T cells often show tissue-specific localisation of oligoclonal subpopulations sharing the same TCR chains. The mechanism of (thymic) selection of γδ T cells is still largely unknown. This sets them apart from the classical and much better known CD4+ helper T cells and CD8+ cytotoxic T cells that express αβ TCRs. They are defined by expression of heterodimeric T-cell receptors (TCRs) composed of γ and δ chains. Gamma delta (γδ) T cells are the prototype of ‘unconventional’ T cells and represent a relatively small subset of T cells in peripheral blood.
