This work was aimed at characterizing the immune landscape of SB NETs. Expression of PD-L1 and programmed death-1 (PD-1) was evaluated by immunohistochemistry in 102 surgically resected, primary NETs of the duodenum, jejunum and ileum. Extent and characteristics of the tumor-associated immune infiltrate were also assessed and investigated in their prognostic potential. We detected the expression of PD-L1 in ≥1 and ≥50%
decreases in anxiety and depressive-like behaviors. Conclusion Our findings suggest that PP administration can mitigate neuroinflammation and ameliorate motor and anxiety and depressive-like behavior deficits following TBI. These results underscore the potential of probiotic interventions as a viable therapeutic strategy to address TBI-induced impairments, emphasizing the need for gender-specific treatment approaches.
