... cancer diagnoses. However, only a minority of patients derive durable benefit and progress with traditional approaches, such as cancer vaccines, remains unsatisfactory. A key to overcoming these barriers resides with a deeper understanding of tumor antigen presentation and the complex and dynamic...

... cellular immunity. This is via their molecular interaction with important immune cell-surface molecules such as antigen-presenting MHC proteins, T-cell co-receptors CD4 and CD8, as well as cytoplasmic molecules such as Lck and PKC (protein kinase C). Moreover, the generation of tetraspanin-deficient mice...

...Ulrike Seifert; Elke Krüger Peptide generation by the UPS (ubiquitin–proteasome system) is rate-limiting in MHC class I-restricted antigen presentation in response to virus-induced IFNs (interferons). In this process, the role of IFN-induced rapid remodelling of the UPS is less defined. IFN...

... the ability to bind Ab effector molecules. Some of these fusions (pepbodies) may also initiate Ab effector functions. We have also genetically inserted T-cell epitopes into Abs with specificity for antigen-presenting cell (APC) surface molecules to target the Ab-T-cell epitope fusions (Troybodies) to APCs...
