Industrial hemp (Cannabis sativa L.) adapts to cadmium stress by reshaping rhizosphere fungal community.

Increasing evidence indicates that plants under environmental stress can actively seek the help of microbes ('cry-for-help' hypothesis). However, empirical evidence underlying this strategy is limited under metal-stress conditions. Here, we employed integrated microbial community profiling in cadmium (Cd) polluted soil and culture-based methods to investigate the three-way interactions between the industrial hemp (Cannabis Sativa L.

PD-L1 promotes tumor metastasis by regulating the infiltration of FGFBP2(+)Tm cells in colorectal cancer.

Tumor-infiltrating lymphocytes can influence tumorigenesis and progression. We found PD-L1 can inhibit the infiltration of memory T (Tm) cells in vivo and in vitro by reducing the secretion of CXCL9, CXCL10 in colorectal cancer. Patients with high PD-L1 expression have minimal Tm cell infiltration, accompanied with a higher incidence of tumor metastasis.
