In the present study, we investigated in vivo the infection and APC functions of dendritic cells (DC) and macrophages (Mphi) after administration of live mycobacteria to mice. Experiments were conducted with Mycobacterium bovis bacillus Calmette-Guerin (BCG) or a rBCG expressing a reporter Ag. Following infection of mice, DC and Mphi were purified and the presence of immunogenic peptide/MHC cla...

Tuberculosis, which is caused by infection with Mycobacterium tuberculosis (Mtb), remains one of the major bacterial infections worldwide. Host defense against Mtb is mediated by a combination of innate and adaptive immune responses. In the last 15 years, the mechanisms for activation of innate immunity have been elucidated. Toll-like receptors (TLRs) have been revealed to be critical for the r...

The purpose of the study was to substantiate effectiveness local combined use miliacil and EHF-therapy in complex treatment purulent wounds lower extremities patients with diabetes mellitus its effect on morphological functional changes tissue defects. Our studies included 96 extremities, localized thigh or leg against background mellitus. In 48 main group, were used wounds, control group only ...

Delayed cutaneous hypersensitivity (DCH) of 12 normal adult subjects to purified protein derivative (PPD) of Mycobacterium tuberculosis, streptococcal streptokinase-streptodornase (SK-SD), and Candida albicans Dermatophytin 0 (DO) was assayed in vivo by skin testing and compared with such in vitro correlates of cellular immunity as lymphocyte transformation (LT) and inhibition of leukocyte migr...

Antigen presenting cells (APC) are critical components of innate immunity and consequently shape the adaptive response. Leukocyte Ig Like Receptors (LILR) are innate immune receptors predominantly expressed on myeloid cells. LILR can influence the antigen presenting phenotype of monocytic cells to determine the nature of T cell responses in infections including Mycobaterium leprae. We therefore...

BACKGROUND In recent years, the impact of antituberculous treatment on interferon (IFN)-gamma response to Mycobacterium tuberculosis antigens has been widely investigated, but the results have been controversial. The objective of the present study was: i) to evaluate longitudinal changes of IFN-gamma response to M. tuberculosis-specific antigens in TB patients during antituberculous treatment b...

ichthyozoonotic mycobacterium spp. poses health risks both to fish and humans. in this study, the presence of ichthyozoonotic mycobacterium spp. was investigated in red mullet (mullus barbatus barbatus) and surmullet (mullus surmuletus), widely caught species in the mediterranean and the aegean sea. a total of 208 fish samples, provided from fishermen of mersin province (turkey) were studied. u...

A 54-year-old male, farmer with a history of dyspnea from 10 years ago, developed increased sputum production, coughing and bloodstreaked sputum and hospitalized for further investigations. He was a current smoker (17pack/year) and oral opium addict. Spirometry revealed severe airflow obstruction with FVC: 45%, FEV1: 31%, and FEV1/FVC: 51%. Considering cheat x-ray findings, the patient underwen...

Direct effects of Helicobacter pylori (H. pylori) on human CD4+ T-cells hamper disentangling a possible bacterial-mediated interference with major histocompatibility complex class II (MHC-II)-dependent antigen presentation to these cells. To overcome this limitation, we employed a previously described assay, which enables assessing human antigen-processing cell function by using murine T-cell h...
