Main lines of investigation. Serologic identification and characterization of novel human tumor antigens. Physiological functions of TNF family cytokines (TNF, LTa, LTb) and the investigation of consequences of TNF blocking in vivo and development of chymeric antibodies for therapeutical blocking of TNF in case of its overexpression in autoimmune and infectious diseases. Improvement of genetic knock-out technology.  Engineering mice with mutant cytochrome C gene.
Participation in research projects (programs) and grant support. The project on identification and characterization of tumor antigens was carried out in close collaboration with Ludwig Institute for Cancer Research, New York, NY, USA; N.N. Blokhin Cancer Research Center, Moscow;  Engelhardt Institute of Molecular Biology, Moscow; Medizinische Klinik, Haematologie-Onkologie, Hospital Nordwest, Frankfurt, Germany. The project on generation of TNF- and lymphotoxin-deficient mice was carried out in collaboration with National Cancer Institute, Frederick, MD, USA and Engelhardt Institute of Molecular Biology, Moscow, Russia. The Department is involved in the organization  "Oncoimmunology" educational program (www.oncoimmunology.ru) sponsored by Cancer Research Institute (New York). Research grants: Ludwig Institute for Cancer Research (LICR), Russian Foundation of Basic Research (RFBR), Federal Agency for Science and Innovations (FASI).

Major research advances. Serologic screening of expression cDNA libraries from renal cancer,  breast cancer, ovary cancer, colorectal cancer cell lines and normal testis (approximately 2000000 clones tested, out of which 443 serologically positive clones were submitted to Cancer Immunome Database, SEREX project) Three novel human cancer antigens were discovered, and seven previously described proteins were shown to be putative cancer antigens [Lagarkova et al., 2000; Kuimov et al., 2001; Shebzukhov et al., 2005a, Shebzukhov et al., 2005b]. We developed an improved method to detect serological responses to tumor-associated antigens (SMARTA) using miniarrays [Lagarkova et al., 2003]. A panel of cancer-specific antigens suitable for serologic diagnostics and monitoring of melanoma, renal cancer, breast cancer, ovary cancer, lung cancer and colon cancer has been established. A sizable collection of clinical specimens  (blood serum samples and tissue specimens from patients with different cancers) has been  characterized for reactivity against  the panel of cancer-specific antigens.

A unique panel of mice with complete and tissue-specific inactivation of tumor necrosis factor (TNF) and lymphotoxin (LT) genes was generated. In particular, physiologic functions of LT produced by B-lymphocytes [Tumanov et al., 2002] and of TNF produced by macrophages and T-cells [Grivennikov et al., 2005], as well as cooperation of TNF and LT in vivo [Kuprash, et al., 2002] have been established. Molecular mechanism of immunosuppressant cyclosporin A influence on expression of LT genes was investigated [Kuprash, et al., 2002]. Mouse monoclonal antibodies against TNF were raised and sequenced [Radko et al., Russ. J. Immunol. 7: 371, 2002], and they are being engineered to us as a TNF inhibitor in vivo. A novel animal model to study the consequences of TNF blockade vivo has been generated: mice “humanized” for  TNF/LT locus. These mice produce human TNF which completely compensates for the loss of its mouse counterpart in immune and host defense functions, lymphoid organs architecture and in models of TNF-mediated systemic toxicity.

Scientific recognition. Perigrinus Award from Berlin-Brandenburg Academy of Sciences (S.A. Nedospasov), Helmholtz-Humboldt Research Award (S.A. Nedospasov), Russian Biochemical Society for Young Scientists Award and European Academy Award (D.V. Kuprash).
