摘要

Studies on the biology of immune cells are mainly focused on their role as immune activators and modulators. In their appropriate cultivation and/or modifications, they have shown abilities for an enhanced expression of specific effective molecules. These properties have characterized them as promising candidates for construction of novel safe vaccines and gene-engineering products on their basis. In this aspect, in the last years, attention is directed towards the development of new safe therapeutic methods and techniques with immune cells. In this connection, according to results obtained,?in vitro-co-cultivation derived by myeloid and lymphoid precursors with positive and negative on the additionally-inserted copy of the oncogene?Dcn1?transfected cells, no immune reaction is observed against both genetically-manipulated cell types, which could be accepted as a proof for their safety. On the other hand, signs of increased degree for both myeloid and lymphoid differentiation in the presence of transfected cells, positive on additionally-inserted copy of the oncogen are indicated.
