Abstract

The effects of applications of recombinant TNF-binding variola virus protein VARV-CrmB in model of contact dermatitis have been investigated. It is shown that VARV-CrmB significantly reduces dinitrochlorbenzene (DNCB)-induced migration of leukocytes (dendritic cells/Langerhans cells) in the afferent phase of contact reaction and the indicator "value ear edema" in the efferent phase of contact reaction. It is known that during inflammation population of proliferating and migrating Langerhans cells replenished by recruitment of bone marrow precursors. Study of bone marrow hematopoiesis in contact dermatitis model showed that the coapplication of DNCB+VARV-CrmB significantly reduced DNCB-induced increase in the number of granulocyte-macrophage colony up to control values. The obtained results suggest the possibility of use of TNF blockers by application in the treatment of inflammatory diseases of the skin.
