Regulation of tumor infiltrated innate immune cells by adenosine

Glioblastoma-infiltrated innate immune cells resemble M0 macrophage phenotype.

Glioblastomas are highly infiltrated by diverse immune cells, including microglia, macrophages, and myeloid-derived suppressor cells (MDSCs). Understanding the mechanisms by which glioblastoma-associated myeloid cells (GAMs) undergo metamorphosis into tumor-supportive cells, characterizing the heterogeneity of immune cell phenotypes within glioblastoma subtypes, and discovering new targets can ...

Regulation of Intestinal Homeostasis by Innate Immune Cells

The intestinal immune system has an ability to distinguish between the microbiota and pathogenic bacteria, and then activate pro-inflammatory pathways against pathogens for host defense while remaining unresponsive to the microbiota and dietary antigens. In the intestine, abnormal activation of innate immunity causes development of several inflammatory disorders such as inflammatory bowel disea...

Endothelial Cells: Directing Innate and Immune Regulation by Microvascular

Recognition of tumor cells by Dectin-1 orchestrates innate immune cells for anti-tumor responses

The eradication of tumor cells requires communication to and signaling by cells of the immune system. Natural killer (NK) cells are essential tumor-killing effector cells of the innate immune system; however, little is known about whether or how other immune cells recognize tumor cells to assist NK cells. Here, we show that the innate immune receptor Dectin-1 expressed on dendritic cells and ma...

Tehranolide Could Shift the Immune Response towards Th1 and Modulate the Intra-Tumor Infiltrated T Regulatory Cells

Background: Artemisia diffusa contains a new type of sesquiterpene lactone with an endoperoxide group (Tehranolide). Objective: Due to the existing similarity between the structures of Tehranolide and Artemisinin, it was hypothesized that Tehranolide would have similar effects as Artemisinin. In this study, the immunotherapeutic effec-tiveness of Tehranolide was investigated by direct intra-tum...
