Adhesion Molecule Regulation Of Regulatory T Cell Migration, Jessica Jean Loppnow Aug 2013

Adhesion Molecule Regulation Of Regulatory T Cell Migration, Jessica Jean Loppnow

Theses and Dissertations

Regulatory T (Treg) cells mediate tumor immune evasion by suppressing anti-tumor effector T cell responses in peripheral lymphoid tissues and within the tumor. While elevated Treg cell numbers have been shown to correlate with increased tumor growth, mechanisms that regulate their distribution within secondary lymphoid tissue and tumor tissue are not well understood. L-selectin, an adhesion molecule constitutively expressed on all classes of leukocytes, functions early in the adhesion cascade and regulates the migration of lymphocytes to lymph nodes through high endothelial venules. In addition, L-selectin can mediate migration of lymphocytes to sites of inflammation by binding to ligands present …

The deregulation of cell signaling is a very important component in the development and progression of cancer. One group of signaling molecules that has been implicated in these processes is the Mitogen-Activated Protein Kinase (MAPK) family which consists of three major branches in mammalian cells: ERK, JNK and p38. The activity of these kinases has wide-ranging effects within the cell and must …
