Deciphering the third branch of adaptive immunity: a quest for gamma delta T cell receptor ligands
Three types of antigen receptors – B cell receptor (BCR), alpha beta T cell receptor (abTCR) and gamma delta T cell receptor (gdTCR) – define the three types of adaptive lymphocytes that constitute the adaptive immune system of all jawed vertebrates. While we know a lot about antigen recognition and functions of B cells and ab T cells, our knowledge on gdTCR specificities and therefore gd T cell functions remains rudimentary. Despite the increasing indirect evidence for recognition of endogenous ligands by gdTCRs, most gdTCRs remain orphan receptors. In an attempt to identify ligands for gdTCRs we utilized a novel reporter system to screen a wide panel of gdTCRs against a collection of cell lines. This resulted in identification of ligand-expressing cells for several gdTCRs. The aim of this master student project will be to search for molecular determinants that are responsible for this reactivity. We are seeking a highly motivated person with a strong desire to study basic principles of immune system function. Successful candidate will join an international team of enthusiastic researcher. A minimum of 4-6 months are required for execution of this ambitious project. Experimental approaches that the student will master include advanced flow cytometry, molecular cloning, cell culture and virus-mediated gene delivery (prior knowledge of some of these technics is an advantage). |
