A highly immunosuppressive tumor microenvironment(TME)and the presence of the blood‒brain barrier are the two major obstacles to eliciting an effective immune response in patients with high-grade glioma(HGG).Here,we tried to enhance the local innate immune response in relapsed HGG by intracranially injecting poly(I:C)to establish a robust antitumor immune response in this registered clinical trial(NCT03392545).During the follow-up,12/27(44.4%)patients who achieved tumor control concomitant with survival benefit were regarded as responders in our *** found that the T-cell receptor(TCR)repertoire in the TME was reshaped after poly(I:C)*** on the RNA-seq analysis of tumor samples,the expression of annexin A1(ANXA1)was significantly upregulated in the tumor cells of nonresponders,which was further validated at the protein *** vitro and in vivo experiments showed that ANXA1 could induce the production of M2-like macrophages and microglia via its surface receptor formyl peptide receptor 1(FPR1)to establish a Treg cell-driven immunosuppressive TME and suppress the antitumor immune response facilitated by poly(I:C).The ANXA1/FPR1 signaling axis can inhibit the innate immune response of glioma patients by promoting an anti-inflammatory and Treg-driven ***,ANXA1 could serve as a reliable predictor of response to poly(I:C),with a notable predictive accuracy rate of 92.3%.In light of these notable findings,this study unveils a new perspective of immunotherapy for gliomas.

Background: Paraplegia after spinal cord ischemia is a devastating condition in the clinic. Here, we develop an awake rabbit model of spinal cord ischemia with delayed paraplegia and explore the influence of ambient temperature on the outcomes after ***: A total of 47 male rabbits were involved in the present study. Transient spinal cord ischemia was induced by occluding the infrarenal abdominal aorta of awake rabbits at different ambient temperatures. To find the optimal conditions for developing delayed paraplegia, hindlimb motor function after ischemia was evaluated between ***: The onset and magnitude of ischemic injury varied with the ambient temperature maintained during the peri-i schemia period. More serious spinal cord injury occurred when ischemia was induced at higher temperatures. At 18°C, 25-minute ischemia resulted in 74% of rabbits developing delayed paraplegia. At a temperature of 28°C or higher, most of the animals developed acute paraplegia immediately. While at 13°C, rabbits usually regained normal motor function without ***: This awake rabbit model is highly reproducible and will be helpful in future studies of delayed paraplegia after spinal cord ischemia. The ambient temperature must be considered while using this model during investigation of therapeutic interventions.
