Stereotactic body radiation therapy (SBRT) concentrates radiation to a predefined target, affecting all the cells within it. Adoptive immunotherapy is not restricted by the major histocompatibility complex (MHC) in recognizing and eliminating target cells. We investigated the effects of the combined modality of SBRT and adoptive immunotherapy on patients with advanced malignant tumors. The data...

BACKGROUND Since the recent introduction of radioimmunotherapy (RIT) using antibodies against cluster of differentiation (CD) 45 for the treatment of lymphoma, the clinical significance of the CD45 antigen has been increasing steadily. Here, we analyzed CD45 expression on lymphocyte subsets using flow cytometry in order to predict the susceptibility of normal lymphocytes to RIT. METHODS Perip...

OBJECTIVE To evaluate the influence of dimethyl fumarate (DMF, Tecfidera) treatment of multiple sclerosis (MS) on leukocyte and lymphocyte subsets. METHODS Peripheral blood leukocyte and lymphocyte subsets, including CD3(+), CD4(+), and CD8(+) T cells; CD19(+) B cells; and CD56(+) natural killer (NK) cells, were obtained at baseline and monitored at 3 months, 6 months, and 12 months after ini...

Vigorous exercise is associated with oxidative stress, a state that involves modifications to bodily molecules due to release of pro-oxidant species. Assessment of such modifications provides non-specific measures of oxidative stress in human tissues and blood, including circulating lymphocytes. Lymphocytes are a very heterogeneous group of white blood cells, consisting of subtypes that have di...

The percentages of T-lymphocytes, lymphocyte subsets CD4+ and CD8+ T-cells, and lymphocyte adhesion molecule CD11a/CD18 were determined in the peripheral blood and cerebrospinal fluid (CSF) of seven normal horses and four horses with equine protozoal myeloencephalitis (EPM) using flow cytometry. There was a greater percentage of CD5+ cells in the CSF (79.0%) than in peripheral blood (67.0%), al...

The role of CD19(+) CD5(+) and CD19(+) CD5(-) B cell subpopulations in the antibody response to pneumococcal capsular polysaccharides (caps-PSs) is controversial. In the present study, we evaluated the role of human CD19(+) CD5(+) and CD19(+) CD5(-) cell populations in the serotype-specific antibody response to caps-PS. After vaccination of 5 healthy human adults with Pneumovax (23-valent pneum...

Proportional changes of lymphocyte subsets in the peripheral blood were monitored by two-color flow-cytometry in seven leukemia patients who had received allogenic bone marrow transplantation (BMT). Lymphocyte counts, and proportions of T and B-cells returned to normal ranges between the 2nd and 12th months after BMT. Activated T-cells prominently increased after BMT, and the values gradually r...

The production of murine monoclonal antibody (MAb) has not yet been reported in Iran. The present work describes for the first time the generation of several murine hybridoma clones secreting MAbs directed against human leukocyte surface antigens. The secreted antibodies by hybridoma clones have been screened on different lymphoid and non-lymphoid tissues. Results indicated that of seven h...
