Article Abstract
Background: Spinal cord injury (SCI) is a devastating disorder. After SCI, it initiates a robust immune response. Considering the spleen is one of the most important immune organs, the present study further characterizes the inflammatory cytokine profile of spleen in acute SCI.
Methods: Adult rats were divided into sham and SCI groups (n = 36). SCI was produced at the T3 vertebral level. The whole blood and spleen was collected at 6, 24, 48, 72, 120, and 168 h after SCI. The levels of the inflammatory factors (IL-1β, IL-6, IL-10, TNF-α, and TGF-β) in spleen and serum were measured with an ELISA kit.
Results: The results showed significantly elevated levels of IL-1β, IL-6, IL-10 and TNF-α in spleen compared with control group levels. Inflammatory cytokine levels of spleen correlated negatively with spleen index.
Conclusion: It was found that inflammatory cytokines in spleen showed dynamic responses to SCI, which suggest their specificity change of spleen caused by SCI. These results suggest that a possible involvement of spleen in the initiation of the inflammatory response after SCI.

Poultry egg production is shaped by the intertwined action of multiple physiological systems, greatly magnifying the complexity of its underlying genetic regulation. Although multitissue mapping of regulatory variants offers a powerful route to untangle this complexity, comprehensive data sets in ducks remain scarce. Meanwhile, the contributions of peripheral systems beyond neuroendocrine regulation on poultry egg production are still largely unexplored.

Type 1 diabetes mellitus (T1DM) is an autoimmune disorder in which autoantibodies cause the immune system to attack and destroy pancreatic β-cells, leading to insufficient insulin production and impaired blood glucose control. T follicular helper (Tfh) cells are recognized as a group of CD4 T cells that help B cells to produce high-affinity antibodies. Our previous research found that oxymatrine (OMT) exhibits excellent immunomodulatory properties on Tfh cells in autoimmune diseases.

Paclitaxel resistance is a major obstacle to achieving long-term remission in patients with triple-negative breast cancer (TNBC), and effective strategies to overcome drug resistance would have significant clinical impact. In this study, we established a paclitaxel-resistant cell clone, T50R, from the human TNBC cell line MDA-MD-231. Intriguingly, these drug-resistant T50R cells required paclitaxel for proliferation.

Turbot (Scophthalmus maximus) is one of the most widely species that boasts high economic value in the aquaculture industry. In spite of the exponential growth of aquaculture, infectious bacterial diseases have caused great economic losses in turbot industry. This study isolated and identified a strain of Pseudomonas putida, denoted as DY16, and it is a conditionally pathogenic bacterium, therefore we conducted the following research on it.
