Abstract:
A double immunolabelling technique was developed to study microscopically the interactions between CD4, CD45 and the T cell receptor on the surface of rat T cells induced by the phenomenon of co-capping. It was found that both CD4 and CD45 passively co-cap with the actively capped T cell receptor, that the T cell receptor and CD45 passively co-cap with CD4, but that neither CD4 nor the T cell receptor co-cap with CD45. Co-crosslinking and active capping of CD45 with either the T cell receptor or CD4 prevented CD4 or the T cell receptor respectively, from passively co-capping. These experiments

Low affinity Fcg receptor III (FcgRIII, CD16) triggers a variety of cellular events upon binding to the Fc portion of IgG.

Results revealed an unusual temperature dependence of reverse rate of CD16aTM dissociating from IgG.

Transgenic mice expressing a T cell receptor specific for cytochrome C in association with I-Ek were employed to study the mechanisms regulating the decision between tolerance and immunity.

Abstract:
B cells recognise antigens on micro-organisms through their B cell receptor (BCR) and via Toll-like receptors (TLRs), and thus respond in both innate and adaptive manners during the subsequent immune response. Innate recognition through TLRs has the potential to alter the behaviour of whole B cell populations. I show, here, that MyD88-dependent activation of B cells via TLR2 or TLR9 causes the rapid loss of expression of CD62L, by metalloproteinasedependent shedding, resulting in the exclusion of these cells from lymph nodes and Peyer’s patches, but not the spleen.

Heart transplantation (HTx) is now an established therapy for end-stage cardiac failure not responding to medical treatment. Recent decades have seen improved outcome following HTx due to more effective and targeted immunosuppressive therapy.

At the same time, immunosuppressive strategies are associated with significant side effects, including development of tumours. Hence, the induction of immunologic tolerance to alloantigen is considered the “holy grail” of transplant research. T regulatory cells (Tregs)

Pathogen recognition by CD8+ T cells occurs through binding of T cell receptors (TCR) to processed antigens in complex with major histocompatibility complex (MHC) class I proteins. TCR engagement of antigens in complex with MHC class I typically lead to cytotoxic CD8+ T cell responses, which result in pathogen clearance. Due to the large number of foreign antigens that might be encountered by any given host a diverse repertoire of TCRs must be available for immune recognition. The main source o

T lymphocytes are essential components of the immune system and as such are continually regulated by a variety of factors. Every step of their development, survival and function is tightly monitored to ensure their ability to recognize most foreign agents and mount adaptive immune responses during pathogenic infections, while remaining tolerant to self-antigens. Among the many factors that participate in the regulation of T cell development and function are the cytokines.
