| Abstract | The dynamics of the expression of the high-affinity receptor for interleukin-2 (IL-2 receptor) evaluated by the method of flow cytofluorimetry based on changes in the number of cells that express the CD25 marker (CD25+) was studied in human peripheral blood lymphocytes stimulated by various mitogens. It has been shown that, in the resting lymphocyte culture, both phytohemagglutinin (PHA, 10 μg/ml) and 12,13-phorbol dibutyrate (PDBu, 10$^{−8}$ M) with ionomycin (IM, 5 × 10$^{−7}$ M) induce a long-lasting increase (for 48 h) in the number of CD25+ cells. Interleukin-2 (IL-2) has only been found to be capable of inducing time-dependent CD25 expression in competent (not resting) lymphocytes pretreated with submitogenic doses of PHA (1 μg/ml). A comparison of the dynamics of the number of CD25+ cells and blast transformation has shown that CD25 markers are revealed as early as on small stimulated lymphocytes, while, at the late activation stages, which correspond to the stage of cell growth and transition to DNA synthesis, the overwhelming majority of blasts are CD25+ cells with high-affinity α -receptors for IL-2. The obtained data allow one to suggest that the expression of an α -subunit of IL-2 receptor takes place at the IL-2-dependent stage of T lymphocyte proliferation and may be directly induced by IL-2 via IL-2 receptor. |

National Digital Library of India (NDLI) is a virtual repository of learning resources which is not just a repository with search/browse facilities but provides a host of services for the learner community. It is sponsored and mentored by Ministry of Education, Government of India, through its National Mission on Education through Information and Communication Technology (NMEICT). Filtered and federated searching is employed to facilitate focused searching so that learners can find the right resource with least effort and in minimum time. NDLI provides user group-specific services such as Examination Preparatory for School and College students and job aspirants. Services for Researchers and general learners are also provided. NDLI is designed to hold content of any language and provides interface support for 10 most widely used Indian languages. It is built to provide support for all academic levels including researchers and life-long learners, all disciplines, all popular forms of access devices and differently-abled learners. It is designed to enable people to learn and prepare from best practices from all over the world and to facilitate researchers to perform inter-linked exploration from multiple sources. It is developed, operated and maintained from Indian Institute of Technology Kharagpur.

NDLI is a conglomeration of freely available or institutionally contributed or donated or publisher managed contents. Almost all these contents are hosted and accessed from respective sources. The responsibility for authenticity, relevance, completeness, accuracy, reliability and suitability of these contents rests with the respective organization and NDLI has no responsibility or liability for these. Every effort is made to keep the NDLI portal up and running smoothly unless there are some unavoidable technical issues.
Ministry of Education, through its National Mission on Education through Information and Communication Technology (NMEICT), has sponsored and funded the National Digital Library of India (NDLI) project.
