PD-L1 antibody enhanced β-glucan antitumor effects via blockade of the immune checkpoints in a melanoma model

Abstract In the tumor microenvironment (TME), one of the major functions of tumor-recruited CD11b+ cells are the suppression of the T-cell-mediated anti-tumor immune response. β-glucan could convert the phenotype of tumor-recruited CD11b+ cells from the suppressive to the promotive, and enhanced their anti-tumor effects. However, β-glucan could enhance the PD-1/PD-L1 expression on

Aureobasidium spp. and their applications in biotechnology

Highlights Abstract Aureobasidium spp. are the dimorphic fungi which have both major yeast cells and minor filamentous cells. Different strains of Aureobasidium spp. can synthesize different enzymes for utilization of a wide range of substrates including various wastes. Aureobasidium spp. also can synthesize many natural products such as pullulan, β-glucan, polymalate, liamocins, siderophores and melanin which have many applications in various sectors of biotechnology. Furthermore, their

β-glucan from Aureobasidium pullulans augments the anti-tumor immune responses through activated tumor-associated dendritic cells

Highlights Abstract Dendritic cells (DCs) are recognized as the most potent antigen-presenting cells, capable of priming both naïve and memory T cells. Thus, tumor-resident DCs (tumor-associated DCs: TADCs) play a crucial role in the immune response against tumors. However, TADCs are also well known as a “double-edged sword” because an immunosuppressive
