Vitamin D transporter (DBP) is a multifunctional protein. Site-specific deglycosylation results in its conversion to group-specific component protein-derived macrophage activating factor (GcMAF), which is capable of activating macrophages. It has been shown that depending on precursor conversion conditions, the resulting GcMAF activates mouse peritoneal macrophages towards synthesis of either pro- (IL-1β, TNF-α-M1 phenotype) or anti-inflammatory (TGF-β, IL-10-M2 phenotype) cytokines.

In this regard, M2 macrophages of the tumor-associated stroma (TAS) are a promising therapeutic target in treating malignant neoplasms. Using FACS assay, we have estimated the CD11b+/Ly-6G+/Ly-6C+ fraction of macrophages from the peritoneum and TAS in intact healthy mice and those with developed Lewis carcinoma, both untreated and treated according to Karanahan technology in combination with group-specific macrophage activator (GcMAF-RF).

Immature hematopoietic progenitors are a constant source for renewal of hemocyte populations and the basic component of the tissue and cell repair apparatus. A unique property of these cells of internalizing extracellular double-stranded DNA has been previously shown. The leukostimulatory effect demonstrated in our pioneering studies was considered to be due to the feature of this cell.

The success of adaptation of students to conditions of educational process in Medical University is determined by complex of accompanying socio-psychological factors. The level of personal anxiety determines severity of impact of these factors on psychosomatic state of student. The high level of anxiety among students in conditions of educating in Medical University can significantly and multi-componently impact their physical organism, success in teaching and social well-being.

The protein is believed to exhibit a wide range of therapeutic properties associated with the activation of macrophagal immunity. An original method for GcMAF production, DBP conversion to GcMAF, and the analysis of the activating potency of GcMAF was developed in this study.
