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...

The paper studies L∞(IR )-norm approximations from a space spanned by a discrete set of translates of a basis function φ. Attention here is restricted to functions φ whose Fourier transform is smooth on IR\0, and has a singularity at the origin. Examples of such basis functions are the thin-plate splines and the multiquadrics, as well as other types of radial basis functions that are employed i...

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 ...

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...

Macrophages can be reprogramming, such as the classical activated macrophage, M1 or alternative activated macrophages, M2 phenotype following the milieu danger signals, especially inflammatory factors. Macrophage reprogramming is now considered as a key determinant of disease development and/or regression. Experimental autoimmune myocarditis (EAM) is characterized by monocytes/macrophage infilt...

background recent studies revealed that tumor-associated macrophages (tams) play a decisive role in the regulation of tumor progression by manipulating tumor oncogenesis, angiogenesis and immune functions within tumor microenvironments. signal transducer and activator of transcription 3 (stat3), which is a point of convergence for numerous oncogenic signalling pathways, is constitutively activa...
