Effects of virally expressed interleukin-10 on vaccinia virus infection in mice (1993)

Kurilla, Michael G., Swaminathan, Sankar, Welsh, Raymond M., Kieff, Elliott D., Brutkiewicz, Randy R.

The monoclonal antibody CZ-1 identifies a mouse CD45-associated epitope expressed on interleukin-2-responsive cells (1993)

Brutkiewicz, Randy R., O'Donnell, Carey L., Maciaszek, Joseph Walter, Welsh, Raymond M., Vargas-Cortes, Mauricio

We have previously described a monoclonal antibody (mAb), CZ-1, which reacts with an epitope expressed on most peripheral basophils, natural killer cells, B cells, and CD8+ T cells, but not with most...

Analysis of and Role for Effector and Target Cell Structures in the Regulation of Virus Infections by Natural Killer Cells: a Dissertation (1993)

Brutkiewicz, Randy R.

The overall emphasis in this thesis is the study of the regulation of virus infections by natural killer (NK) cells. In initial analyses, vaccinia virus (VV)-infected cells were found to be more...

Window of vulnerability of vaccinia virus-infected cells to natural killer (NK) cell-mediated cytolysis correlates with enhanced NK cell triggering and is concomitant with a decrease in H-2 class I antigen expression (1992)

Brutkiewicz, Randy R., Klaus, Stephen J., Welsh, Raymond M.

A time course study was performed in order to determine if vaccinia virus (VV)-infected targets were more susceptible to murine natural killer (NK) cell-mediated lysis during a discrete period of...

Selective Loss of Natural Killer T Cells by Apoptosis following Infection with Lymphocytic Choriomeningitis Virus

Hobbs, Jacqueline A., Cho, Sungyoo, Roberts, Tonya J., Sriram, Venkataraman, Zhang, Jianhua, Xu, Ming, ...

Natural killer T (NKT) cells, a unique subpopulation of T cells, coexpress markers also present on NK cells and recognize the major histocompatibility complex class I-like CD1d1 molecule. We studied...

Inhibition of glycolipid shedding rescues recognition of a CD1+ T cell lymphoma by natural killer T (NKT) cells

Sriram, Venkataraman, Cho, Sungyoo, Li, Ping, O'Donnell, Patrick W., Dunn, Claire, Hayakawa, Kyoko, ...

Neoplastic transformation of cells is accompanied by an aberration of cell surface glycolipid composition. These tumor-associated, altered glycosphingolipids are often shed into the tumor cell...
