OBJECTIVE: The microenvironment of colon cancer (CC) is heterogeneous including cells myeloid lineage affecting tumor growth and metastasis. Two functional subtypes have been identified; one (M1) tumor-inhibitory the other (M2) tumor-promoting. Whether three markers EMR1, CD206 CD86 are expressed only in infiltrating or also was investigated. METHODS: Expression investigated CC at mRNA protein ...

The immunoadhesin (OX2:Fc) comprising the extracellular domain of murine OX2 linked to IgG2aFc, inhibits production of IL-2 and IFN-gamma by activated T cells and increases allograft and xenograft survival in vivo. Increased expression of OX2 on dendritic cells (DC) in vivo following preimmunization via the portal vein is also associated with elevated expression of MD-1. We have used antisense ...

Microglia activation is recognized as the hallmark of neuroinflammation. However, the activation profile and phenotype changes of microglia during the process of retinal degeneration are poorly understood. This study aimed to elucidate the time-spatial pattern of microglia distribution and characterize the polarized phenotype of activated microglia during retinal neuroinflammation and degenerat...

AIMS To construct and evaluate rats' tolerogenic dendritic cells (DC) through induction by NF-κB Decoy method. METHODS GM-CSF and IL-4 were used to transform rats's monocytes into DC, and DC were stimulated with LPS, NF-κB Decoy ODN, and loaded with Bovine Type II Collagen. The following methods were employed to phenotype DC: 1) Observation of cell morphology; 2) Evaluation of cell viability ...

Depletion of B cells in rheumatoid arthritis is therapeutically efficacious. Yet, the mechanism by which B cells participate in the inflammatory process is unclear. We previously demonstrated that Ag-specific B cells have two important functions in the development of arthritis in a murine model of rheumatoid arthritis, proteoglycan (PG)-induced arthritis (PGIA). PG-specific B cells function as ...
