Leukotrienes (LTs) are pro-inflammatory mediators that contribute to the pathophysiological features of asthma. The relationship between the amounts of LTB4 and LTC4 produced by the leukocytes of asthmatic patients on the one hand and immunoglobulin E (IgE)-mediated allergy, asthma exacerbations and bronchial hyperresponsiveness was studied. Leukocytes were obtained from peripheral blood drawn ...
BACKGROUND Understanding how leukocytes in the cervicovaginal and colorectal mucosae respond to pathogens, and how medical interventions affect these responses, is important for developing better tools to prevent HIV and other sexually transmitted infections. An effective cryopreservation protocol for these cells following their isolation will make studying them more feasible. METHODS AND FIN...
Parkinson's disease (PD) is a very common neurodegenerative disease among the elderly population. Current treatments for Parkinson’s disease are based on symptom therapy but not the underlying cause of the disease. This disorder is caused neuronal death which triggers the activation of resident glial cells. This situation leads to neuroinflammation in the central nervous system. Activated...
Background. Exercises with different intensities can cause changes in immune system factors and hormonal acute response. These changes may exceed the permissible limitations and weaken the system. Objectives. The purpose of this study was to compare the effect of an intensity aerobic and anaerobic training session on acute hormonal response and immune system factors. Methods. A total of...
Using simultaneous recording of aggregation and chemiluminescence, responses of human polymorphonuclear leukocytes, blood platelets and their mixture were investigated after stimulation by specific as well as non-specific stimuli for each cell. In our experimental settings, aggregation of platelets and PMN leukocytes was increased in the following order of stimuli: PMA<A23187<thrombin and FMLP<...
Monocyte chemotaxis is severely depressed in patients with advanced tumors, but the cellular basis for this chemotactic defect is not known. Because the actomyosin cytoskeleton is thought to play a primary role in chemotaxis, we have employed flow cytometry to examine several aspects of the contractile machinery including myosin II, myosin light chain kinase (MLCK), actin, and cytoplasmic calci...
