Positive Selection of Thymocytes
Annual Review of Immunology, 1995Differentiation of αβ T cell receptor (TCR)-expressing T cells involves an obligatory interaction with self-major histocompatibility complex (MHC) molecules in the thymus. This process, called positive selection, both rescues thymocytes from programmed cell death and induces their differentiation into mature T cells.

Critical Reviews in Biotechnology, 2002
This review describes information concerning positive selection vectors on their mechanism, classification, property, and limitation. A total of 72 positive selection vectors collected were discussed. Positive selection vectors can reduce background and directly screen transformants containing cloned DNA fragments.

The use of a new mode of selection-positive selection-has been demonstrated to be successful in a large variety of monocot and dicot species. This selection differs from more traditional modes of selection in which compounds such as antibiotics or herbicides are used to kill nontransformed cells (negative selection).

Raf regulates positive selection
European Journal of Immunology, 1996AbstractT cell development is regulated by extracellular signals that mediate cellular proliferation and differentiation via specific signal transduction pathways. To determine the importance of the mitogen‐activated protein kinase (MAP kinase) pathway in thymocyte development, we analyzed transgenic mice expressing dominant negative Raf (DN Raf) and a
