Mary Markiewicz to present Biochemistry and Molecular Biophysics Seminar
Submitted by Biochemistry and Molecular Biophysics
Mary Markiewicz, professor of microbiology, molecular genetics and immunology at the 1xbet online casino of Kansas Medical Center, will be the featured speaker for this week’s Biochemistry and Molecular Biophysics Seminar.
Markiewicz will present "NKG2D ligand expression on 1xbet online casino induces NKG2D-mediated cross-tolerization of cytokine signaling and reduces NK cell tumor immunity" at 4 p.m Wednesday, April 10, in Room 120 of Ackert Hall.
Studies support a role for natural killer, or NK, cells in cancer control, making these cells attractive for immunotherapy. One method being tested to make effective 1xbet online casino is the ex vivo activation with interleukin (IL)-12, IL-15, and IL-18. We demonstrate that this induces NKG2D ligands on 1xbet online casino . By engaging NKG2D, this eliminates the ability of both mouse and human 1xbet online casino to control tumor growth in vivo and in vitro, respectively.
NKG2D-NKG2D ligand interaction between mouse 1xbet online casino reduced NK proliferation and expression of CD25, tumor necrosis factor, or TNF, interferon (IFN)-gamma and T-bet. NKG2D signaling induced between human 1xbet online casino similarly decreased IFN-gamma, but did not affect T-bet or CD25, and increased TNF. These data demonstrate that NKG2D signaling can cross-tolerize cytokine signaling and suggest that eliminating this signaling could be beneficial in NK cell adoptive therapy. Further, these results highlight a need to better delineate effects downstream of NKG2D signaling in human, rather than mouse, 1xbet online casino .
