Agaricus blazei murill (ABM) mainly exerts its antitumor effect via modulation of the immune system. However, the immunomodulatory role of the ABM polysaccharide (ABMP) in mice with subcutaneously and intraperitoneally implanted MC38 tumor remains to be explored. This study aimed to define the progression effect of inhibiting tumor of ABMP in subcutaneous and intraperitoneal models and its effect on tumor microenvironment (TME) metabolism.

To evaluate the CD8 T function enhancing role of polysaccharide compounds, the MC38-N4/OT-I co-culture system was established. The synergistic and complementary immune effect of α-glucopyranose-rich compound polysaccharides can be achieved by manipulating the antigen-specific T-cell expansion capacity and efficacy.

Proper vacancy engineering is considered as a promising strategy to improve intrinsic activity, but it is challenging to construct rich vacancies by a simple strategy. Herein, Fe doped NiP nanosheet arrays with rich P vacancies are developed via a facile phase transformation strategy. Based on systematic investigations, we have demonstrated that an optimized surface electronic structure, abundant active sites and improved charge transport capability can be effectively achieved by vacancy engineering.

Here, rich P vacancies to modulate NiP/CuP interfaced nanosheets for overall water splitting is demonstrated. We conduct a series of experimental parameters to adjust the nanostructures of NiP/CuP, and to get insight into the synergistic effects of interfaces and P vacancies on the catalytic activities.

Constructing heterointerfaces in heterostructures could effectively enlarge the electroactive sites and enhance the interfacial charge transfer, and thus improve the electrocatalytic performances. Herein, free-standing porous NiP-NiP heterostructured arrays are successfully prepared through in situ phosphating Ni(OH) arrays by simply tuning the reaction temperatures. Contributing from the interfacial coupling effects of two phases, large surface areas, highly conductive support of carbon cloth substrates and unique free-standing arrays, NiP-NiP heterostructured arrays show the enhanced kinetics and electrocatalytic performances for the hydrogen evolution reaction, oxygen evolution reaction and overall water splitting.
