Abstract The ovary contains numerous macrophages, and macrophage depletion in mice leads to dysfunctional ovulation. Macrophage function the is presumed be related efferocytosis, however, absence of macrophages also disrupts follicular development corpus luteum development. Granulosa cells (GC) are critical ovarian follicle survival, we hypothesized that macrophage-GC crosstalk promoted GC func...

Two groups of antibodies against mouse resident alveolar and peritoneal macrophages have been raised individually in rabbits by immunization with whole cell suspensions of lavaged alveolar and peritoneal macrophages. The whole antisera reacted positively with neutrophils and lymphocytes. However, upon extensive absorptions with these cells the activity became restricted to macrophages. The...

Abstract Macrophage plasticity and functional activation are critical to the broad array of macrophage-mediated functions that help determine disease outcomes. galactose-type lectin (MGL), a type-2 C-type receptor (CLR) primarily expressed on myeloid cells, has been shown play an anti-inflammatory role in innate response some infectious agents. Our lab recently demonstrated MGL-1 contributes an...

The mycobacterial ESX-1 virulence locus accelerates macrophage recruitment to the forming tuberculous granuloma. Newly recruited macrophages phagocytose previously infected apoptotic macrophages to become new bacterial growth niches. Granuloma macrophages can then necrose, releasing mycobacteria into the extracellular milieu, which potentiates their growth even further. Using zebrafish with gen...

High yields of mouse macrophage-melanocyte heterokaryons and macrophage-macrophage homokaryons were obtained through the virus-induced fusion of cells spread on a glass surface. After fusion there was a striking reorganization of cellular architecture by means of a colcemid-sensitive process. Heterokaryons were isolated through the use of differential trypsinization and many underwent division ...

OBJECTIVE Inflammation is critical for the development of obesity-associated metabolic disorders. This study aims to investigate the role of mitogen-activated protein kinase phosphatase 2 (MKP-2) in inflammation during macrophage-adipocyte interaction. METHODS White adipose tissues (WAT) from mice either on a high-fat diet (HFD) or normal chow (NC) were isolated to examine the expression of M...

Background: Macrophages activation is the important anti-leishmania immune response. Different signals could affect macrophages development and functional activation. Objectives: In the present study, we compared the effect of Leishmania Soluble Antigen (LSA)and Lipopolysaccharide (LPS) on peritoneal macrophage responses. Appropriate activation of macrophages depends on thesignals they receive ...

background: pentavalent antimonials are still the first choice treatment for leishmaniasis, but with low efficacy and resistance is emerging. in the present study, the effect of meglumine antimoniate (ma, glucantime) combined with paromomy-cin, miltefosine or allopurinol on in vitro susceptibility of leishmania tropica resistant isolate was evaluated. method : the drugs were obtained from comme...

quinazolinones are heterocyclic and water insoluble compounds with various pharmacological and biological characteristics (antibacterial, antiswelling, antifungal, parkinson and etc.). they are used for treatment hiv and cancer. this study investigated the effects of 4(3h) quinazlonones-2-ethyl-2-phenyl ethyl (qepe) as a new quinazolinons compounds on the spleen and immunocompetent cells of new...

The histiocytoses are a group of proliferative disorders of themonocyte-macrophage lineage that are neoplastic or reactive innature. Based on immunophenotyping and electron microscopy,two main groups have been recognized namely 1) Langerhanscell histiocytosis (LCH) and 2) non- Langerhans cell histiocytosis(non-LCH). In this study, a fairly rare disease of the non-LCHgroup, generalized eruptive ...
