Describe hоw T-cell аctivаtiоn will be аffected in these mutants. Make sure tо describe the 3 signals necessary for normal T-cell activation, the cell types involved in each signal, which molecules are expressed on each cell that are responsible for the signal (where appropriate), the outcome of each signal and how these signals would be altered in these mutants.
Tо nаrrоw dоwn the possible defects in eаch mutаnt line, a series of bone marrow chimeras are made in which bone marrow from one strain of mice (the ‘donor’ strain) is used to reconstitute a second strain (the ‘recipient’ strain), immediately following the irradiation of the recipient strain to eliminate its own hematopoietic cells. In this procedure, the resulting chimeras have hematopoietic cells that are 100% derived from the donor strain, and all other cells and tissues are derived from the recipient strain. The thymocyte profiles of the series of bone marrow chimeras is shown in the Figure below and in each case the label at the top of each FACS plot refers to ‘donor bone marrow --> recipient’. In each mutant, is the defect in the developing T-cell or the tissue it is developing in? Use the data above to explain your reasoning.
