Neutrophils are rapidly and massively recruited to sites of microbial infection, where they can influence the recruitment of dendritic cells. Here, we have analyzed the role of neutrophil released chemokines in the early recruitment of dendritic cells (DCs) in an experimental model of Leishmania major infection. We show in vitro, as well as during infection, that the parasite induced the expres...

Neutrophils generated by granulocyte colony-stimulating factor (GCSF) are functionally immature and, consequently, cannot effectively reduce infection and infection-related mortality in cancer chemotherapy-induced neutropenia (CCIN). Am80, a retinoic acid (RA) agonist that enhances granulocytic differentiation by selectively activating transcription factor RA receptor alpha (RARα), alternativel...

To understand the gene expression of CAP18 (18-kDa cationic antibacterial protein), a member of cathelicidins, we evaluated mRNA and protein expression of CAP18 using human bone marrow cells and mature neutrophils. Northern blot analysis revealed that CAP18 mRNA was expressed more abundantly in bone marrow cells than mature neutrophils, whereas Western blot analysis indicated that CAP18 protein...

Tuberculosis (TB) disease may progress at different rates and have different outcomes. Neutrophils have been implicated in TB progression; however, data on their role during TB are controversial. In this study, we show that in mice, TB progression is associated with the accumulation of cells that express neutrophilic markers Gr-1 and Ly-6G but do not belong to conventional neutrophils. The cell...

Benign retroviral infections are common but are usually not recognized. This histologic and ultrastructural study identifies such an infection that became clinically evident in the small bowel following a partial colectomy for multiple micro invasive adenomas. Suspected is a low-grade retroviral infection of myeloid progenitor cells activated by inflammatory cytokines released by the operative ...

Human myeloid maturation proceeds within the bone marrow and results in a mature neutrophil that is released into the peripheral circulation. Previous reports have indicated that neutrophils from bone marrow demonstrate decreased adherence, impaired phagocytosis, and decreased nitroblue tetrazolium dye reduction when stimulated. Due to lack of a suitable method for isolating purified bone marro...

Background: Acute respiratory distress syndrome (ARDS) is a severe critical condition with high mortality that currently in focus given it associated caused by coronavirus disease 2019 (COVID-19). Neutrophils play key role the lung injury characteristic of non-COVID-19 ARDS and there also accumulating evidence neutrophil mediated patients who succumb to infection acu...

Survivin, which is a member of the inhibitor of apoptosis protein family, was found originally in immature cells and cancer cells but not in non-neoplastic adult tissues. The subsequent identification of four other alternative splice variants that possess distinct functions and localizations suggested the diverse roles of survivin isoforms. An unspecified isoform of survivin was found recently ...

statement of problem: papillon lefevre syndrome (pls) is a rate autosomal recessive disorder, which is characterized by palmar- plantar hyperkeratosis and rapid periodontal destruction of primary and permanent dentitions. purpose: the aim of the present study was to evaluate the peripheral blood neutrophil function including random locomotion, chemotaxis and oxidative mechanism of killing in a ...
