the adaptive response (ar) is a phenomenon by which cells exposure to sublethal doses of dna-damaging agents (non-mutagenic dose of chemical or radiation), known as conditioning treatment (ct), leads to increased resistance to a subsequent exposure to a higher dose of the same or other agents, known as challenge treatment (cr). the adaptive response (ar) induced by radiation in human lymphocyte...
The effects on the mitogenic response of human T lymphocytes were studied for 20 different antibiotics. No apparent inhibitory effect could be detected for penicillins, cephalosporins, aminoglycosides, chloramphenicol, sulfamethoxazole, trimethoprim, nalidixic acid, and 5-fluorocytosine. There were effects at high concentrations with erythromycin, clindamycin, and rifampin, and these antibiotic...
OBJECTIVE Approximately 90% of squamous carcinomas of the cervix harbor the human papillomavirus and type 16 has been detected in nearly 50% of cases. Recent studies in mice have shown that the human papillomavirus type 16 E7 oncoprotein contains peptide epitopes that are processed and presented in association with a major histocompatibility antigen for recognition by cytolytic T lymphocytes. W...
background: a radioprotective effect of amifostine as well as its ability to modulate the level of spontaneous and gamma-irradiation-induced genetic changes on human peripheral blood lymphocytes has been investigated . amifostine, known as a potent radical scavenger, has been introduced as the most effective radioprotector, yet it is not completely approved for the clinical use. however, furthe...
the immune responses that develop following epstien-barr virus (ebv) infection are complex and involve both humoral and to a greater extent cell-mediated immune mechanisms. to evaluate the immune response, flow cytometric analysis of the peripheral blood of six patients during the acute phase of ebv infection was performed. this analysis revealed a significant increase in the percentages and th...
Genotyping of the highly polymorphic cytochrome p450 2D6 (CYP2D6) permits a gross classification of individual phenotype (viz. ultra-rapid, extensive, and poor metabolizers). It does not, however, provide a precise prediction of CYP2D6 activity, particularly in an individual possessing at least one functional CYP2D6 allele. It has been suggested that the level of mRNA expression or enzyme activ...
The present study was aimed to evaluate the possibility of using anti-human monoclonal antibody CD3 as pan T-cell marker in guinea pigs’ trachea and lung early late manifestations allergic inflammatory process.

1 Irbesartan is a promising antihypertensive drug with beneficial effects on atherosclerotic processes. In the progression of atherosclerosis, human T-lymphocytes play an important role, but it is not yet known how irbesartan modulates human T-lymphocytes activation. To gain insight into the mechanisms by which irbesartan acts, we investigated its effects on human T-lymphocytes. 2 Primary human...
