Type of Research Project
- Basic science
What is the background of the project?
T cells recognize peptides in combination with major histocompatibility complex (MHC) molecules on antigen presenting cells (APC). The interaction between MHC molecules and the T cell receptor (TcR) delivers an signal to the T cell. It seems possible that the engagement of the MHC molecule by the TcR can also deliver a signal to the APC. Such signals might be relevant for instance in the context of reciprocal antigen presentation between T cells. It is known that this special form of antigen presentation can lead to an unusual T cell activation which can result in so-called bystander lysis of target cells T cells without necessity for antigen presentation by these bystander cells. This form of T cell activation might have implications for virus infections and cancer.
What is the aim of the project?
The project aims in the analysis of the effects of stimulation of MHC molecules on lymphocytes in vitro.
What techniques and methods are used?
Primary human lymphocytes will be isolated from blood from healthy donors. MHC stimulation will be performed with immobilized antibodies. Gene expression of cells after stimulation will be analyzed with quantitative reverse transcription-polymerase chain reaction and flow cytometry (and - depending on the results - microarrays).
