The atomic force microscopy of morphological and biophysical features of peripheral blood lymphocytes in different types of diabetes mellitus

The atomic force microscopy (hereinafter - AFM) is one of the leading applications of Nanotechnological research methods of cell membranes widely used in key areas of biomedicine. The study of the biophysical properties of the membrane and morphological parameters of lymphocytes by AFM can provide essential information about the patterns of structural change of the cytoplasmic membrane in the development of diabetes, disorders of metabolism, microcirculation and immunity. The purpose of this study was to investigate a number of morphological and biophysical characteristics of blood lymphocytes of patients with diabetes mellitus by AFM. The material of the study was lymphoid cells of peripheral blood of patients with insulin-dependent (IDDM) and non-insulin dependent type of diabetes mellitus (NIDDM), and healthy volunteers. For analysis of the membrane of lymphocytes was used a scanning probe microscope Solver P47-PRO (NT-MDT, Russia). Scanning cell surface of the membrane of blood lymphocytes were performed using silicon probes series PNP-DB-20 (NT-MDT) with a hardness of 0...
