A similar defect host defense mechanisms in hairy cell leukemia was defined in two patients. Surface-adherent monocytes were not detected in the peripheral blood nor were monocytes that mediate antibody-dependent cell-mediated cytotoxicity (ADCC) to isoantibody-coated human erythrocytes. In addition, lymphocytes of both patients failed to show blastogenic responses to concanavalin A (Con-A) and...

Abstract Neutrophils are often the major leukocyte at sites of mycobacterial infection, yet little is known about their ability to kill mycobacteria. In this study we have investigated whether potent antibacterial oxidant hypochlorous acid (HOCl) contributes killing Mycobacterium smegmatis when bacterium phagocytosed by human neutrophils. We found that M. were ingested neutrophils into intracel...

Tuberculosis is a current major world-health problem, exacerbated by the causative pathogen, Mycobacterium tuberculosis (Mtb), becoming increasingly resistant to conventional antibiotic treatment. Mtb is able to counteract the bactericidal mechanisms of leukocytes to survive intracellularly and develop a niche permissive for proliferation and dissemination. Understanding of the pathogenesis of ...

Introduction: Non-tuberculous species of Mycobacterium are a large group of Mycobacterium and are widely distributed throughout the world. Increased isolation of non-tuberculous mycobacteria from patients with mycobacteria infections in Iranian laboratories was associated with erroneous and unnecessary drug treatment, so that in some cases isolated strains considered as drug resistant strains. ...

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...

kcnk2 was previously shown to regulate immune-cell trafficking into the central nervous system (cns). kcnk2-/- mice demonstrated a more severe disease course in experimental autoimmune encephalomyelitis, an animal model of multiple sclerosis, due to an increased immune-cell migration into the cns. an upregulation of the cellular adhesion molecules icam1 and vcam1 on brain endothelial cells in k...
