Intensity of HLA-A2 Expression Significantly Decreased in Occult Hepatitis B Infection.

Background: Occult hepatitis B infected (OBI) patients cannot eradicate hepatitis B virus (HBV)-DNA from their liver and peripheral blood, completely.

Objectives: The main aim of this study was to investigate the rate of HLA-A2 expression on peripheral blood mononuclear cells (PBMCs) of patients with OBI.

Materials And Methods: In this experimental study, intensity of HLA-A2 was measured on the PBMCs of 57 OBI patients and 100 HBsAg-/anti-HBc+/HBV-DNA samples were enrolled as controls; measurements were performed using the flow cytometry technique.

All eotaxins CCL11, CCL24 and CCL26 are increased but to various extents in pulmonary tuberculosis patients.

Background: Mycobacterium tuberculosis is a pulmonary pathogen responsible for tuberculosis. Tuberculosis (TB) is characterized histologically by granulomas at the site of disease activity. Primary pathologic feature of TB is formation of a granuloma, and chemokines are known to play an important role in the formation of granulomas during infection.

Dose Ramadan Fasting Affects Inflammatory Responses: Evidences for Modulatory Roles of This Unique Nutritional Status via Chemokine Network.

Objective(s): The impact of fasting in Ramadan as a unique type of nutritional regimen on biochemical and hematological parameters is still an issue of debate. Almost very little is known regarding the regulatory role(s) of this nutritional status on immune responses or inflammation.

Materials And Methods: The levels of biochemical parameters were determined using commercial diagnostic kits.
