“…Move from cancer to inflammation, Koga et al [9] presented a platelet-activating factor receptor (PAFR) and signal transducer and activator of transcription 3 (STAT3) dependent signal pathway of IL-10 production by dendritic cells (DCs) during LPSstimulation. To understanding DCs better, Lin and Wang [10] briefly reviewed the roles of cytoskeletal actin and its regulators in the function of DCs, especially during the viral infections.…”

Immunobiology focuses on the biological processes in the immune system of organisms and helps us understanding and treating diseases, such as bacterial [1] and viral [2] infections, inflammation [3], cancer [4,5], auto-immune diseases [6] and chronic diseases [7]. The advanced investigations in immunobiology strive to both understand how the immune system protects our body and translate the basic immunological perspectives to clinics. Journal of Immunobiology updates the frontier advancements of immunological researches and provides perspectives in multiple fields of immunology and diseases.The current issue of the Journal of Immunobiology presents interesting studies that could update our current knowledge. Using an in vitro system, Lin and Lin [8] investigated the effects of different natural polysaccharides on the chemokine mediated immune therapy of human breast cancer. Move from cancer to inflammation, Koga et al.[9] presented a platelet-activating factor receptor (PAFR) and signal transducer and activator of transcription 3 (STAT3) dependent signal pathway of IL-10 production by dendritic cells (DCs) during LPSstimulation. To understanding DCs better, Lin and Wang [10] briefly reviewed the roles of cytoskeletal actin and its regulators in the function of DCs, especially during the viral infections.Breast cancer is the most frequently diagnosed malignancy in women [11]. Polysaccharides have been shown as a potential drug in treating cancers [12][13][14]. To investigate the killing effects of various polysaccharides on breast cancer cells, Lin and Lin [1] has purified polysaccharides from five different sources-guava, common buckwheat, bitter buckwheat, red formosa lambsquarters, and yellow formosa lambsquarters. None of these polysaccharides showed any effects on the viability and growth of breast cancer MCF-7 cells. Surprisingly, the polysaccharide-treated-splenocyte-conditioned media (SCM) showed an anti-cancer effect by inducing cell death. Cytokine measurements demonstrated that the production of IL-2 and IL-10 by splenocytes is induced by most polysaccharides, and the ratio of IL-10 vs. IL-2 was increased in a dose-dependent manner. Association assay suggest that the anti-cancer effect is mediated by the increase of IL-10 and IL-10/IL-2 ratio in SCM after polysaccharide stimulation. This study brings insights of immune regulation into the anti-cancer therapy by polysaccharides.Platelet-activating factor (PAF) is a lipid mediator that is known to be involved in platelet aggregation and inflammation. PAF acts by binding to a unique G protein-coupled seven transmembrane-plateletactivating factor receptor (PAFR), and activates multiple intracellular signaling pathways [15]. It is known that in dendritic cells (DC) and macrophages, exogenous PAF in conjunction with LPS induces the production of IL-10. However, the molecular mechanism remains unclear. Using inhibitors and gene editing, Koga et al. [2] investigated the mechanisms underlying the production of IL-10 upon PAFR activation. This study showed th...
