CYTOKINE REGULATION IN THE COURSE OF MULTIPLE MYELOMA PROGRESSION

Cytokines are wide-range modifiers of biological reactions. Cytokine regulation provides proliferation, differentiation, cell function, cell-cell and inter-systemic interaction, direction and nature of immune response to invasion of infectious and non-infectious pathogens. There are several distinct...

Cytokine regulation provides proliferation, differentiation, cell function, cell-cell and inter-systemic interaction, direction and nature of immune response to invasion of infectious and non-infectious pathogens.

Our study involved 101 patients with MM (IgG-variant), their age ranging between 40 and 76 years. The diagnosis was verified by clinical and laboratory examinations. The G-variant of MM was verified by immunofixation and electrophoresis. The definite diagnosis and disease staging was confirmed by a combination of diagnostic criteria.
