Background: Falciparum malaria is a severe health burden worldwide. Antigen presenting cells are reported to be affected by erythrocytic stage of the parasite. Malarial hemozoin (HZ), a metabolite of malaria parasite, has adjuvant properties and may play a role in the induction of immune response against the parasite. Objective: To determine the immunological impact of hemozoin on the capacity ...

Neutrophils are part of the first line of immune response and are essential for resistance against a variety of pathogens. They professionally mediate direct killing of pathogens, recruit other phagocytes by specific chemokines, produce cytokines and interact with different immune cells to shape the adaptive response. Leishmania as an obligatory intracellular parasite has evolved to benefit thi...

Abstract Summary: Natural killer (NK) cells accumulate at the fetal–maternal interface and represent 70% of immune in decidua (dNK) first-trimester pregnancy; they are immune-tolerant toward semiallogenic fetus “nurturing” nonkilling NK cells. A subset patients with cancer have features common dNK, which include expressing CD56, CD9, CD49a, CXCR3, being poorly cytotoxic proangiogenic, mimicking...

results cloning and subcloning of the flic gene were confirmed by colony pcr, restriction enzymes digestion and dna sequencing of the recombinant plasmids pprime-flic and pvax-flic. the expression of flagellin protein in eukaryotic cells was approved by immunofluorescence assay (ifa), western blotting analysis and the reverse transcriptase polymerase chain reaction (rt-pcr) method. conclusions t...

Dear Editor, Cigarette smoking has destructive effect on periodontal tissue. The rates of loss of periodontal attachment and recession of gingival are higher in smokers than non-smokers (1-2). Previous studies on the inflammatory immune responses in smokers’ periodontitis have mainly focused on the role of neutrophils. Tumor necrosis factor–α, prostaglandin E2 and matrix metalloproteinase...

conclusion mature biofilms were found to be much more resistant to antifungal agents and the host immune system than free cells. the factors responsible for high resistance included the complex architecture of biofilms, ecm, increased expression of drug efflux pumps, and metabolic plasticity. objectives the present work investigated certain aspects of the resistance of c. albicans biofilms to d...

Background: Evidence indicates that neuropathic pain pathogenesis is not confined to changes in the activity of neuronal systems but involves interactions between neurons, inflammatory immune and immune-like glial cells. Substances released from immune cells during inflammation play an important role in development and maintenance of neuropathic pain. It has been found that minocycline suppress...
