Theses cells are crucial in the pathogenesis of juvenile idiopathic arthritis. A polymorphism in its promoter region and the genotype IL12p40 pro1.1 leads to a higher production of IL-12p40. We studied whether there is a difference in the distribution of the genotype in patients with JIA and the healthy population. Methods: In 883 patients and 321 healthy controls the IL-12p40 promoter genotype was identified by ARMS-PCR. Results: There is no association of IL-12p40 pro polymorphism neither in patients with JIA compared to controls nor in subtypes of JIA compared to oligoarthritis. We found a non-significant tendency of a higher prevalence of the genotype pro1.1 in systemic arthritis (32.4 \%) and in rheumatoid factor negative polyarthritis (30.5 \%) and a lower pro1.1 genotype in persistent oligoarthritis (20.7 \%) and in enthesitis-related arthritis (17 \%). Likelihood of the occurrence of genotype IL12-p40 pro1.1 in patients with systemic arthritis (OR 1.722, CI 95 \% 1.344-2.615, p 0.0129) and RF-negative polyarthritis (OR 1.576, CI 95 \% 1.046-2.376, p 0.0367) compared to persistent oligoarthritis was significantly higher. This was also true for comparison of their homozygous genotypes IL-12p40 pro 1.1 and 2.2 in systemic arthritis (OR 1.779, CI 95 \% 1.045-3.029, p 0.0338). However, in Bonferroni correction for multiple hypothesis this was not significant. Conclusion: A tendency of a higher prevalence of the genotype IL-12p40 pro1.1 in systemic arthritis and in rheumatoid factor negative polyarthritis was observed but not significant. Further investigations should be done to clarify the role IL-12p40 in the different subtypes of JIA.}, language = {en} } @article{LuuRiesterBaldrichetal.2021, author = {Luu, Maik and Riester, Zeno and Baldrich, Adrian and Reichardt, Nicole and Yuille, Samantha and Busetti, Alessandro and Klein, Matthias and Wempe, Anne and Leister, Hanna and Raifer, Hartmann and Picard, Felix and Muhammad, Khalid and Ohl, Kim and Romero, Rossana and Fischer, Florence and Bauer, Christian A. and Huber, Magdalena and Gress, Thomas M. and Lauth, Matthias and Danhof, Sophia and Bopp, Tobias and Nerreter, Thomas and Mulder, Imke E. and Steinhoff, Ulrich and Hudecek, Michael and Visekruna, Alexander}, title = {Microbial short-chain fatty acids modulate CD8+ T cell responses and improve adoptive immunotherapy for cancer}, series = {Nature Communications}, volume = {12}, journal = {Nature Communications}, doi = {10.1038/s41467-021-24331-1}, url = {http://nbn-resolving.de/urn:nbn:de:bvb:20-opus-309332}, year = {2021}, abstract = {Emerging data demonstrate that the activity of immune cells can be modulated by microbial molecules. Here, we show that the short-chain fatty acids (SCFAs) pentanoate and butyrate enhance the anti-tumor activity of cytotoxic T lymphocytes (CTLs) and chimeric antigen receptor (CAR) T cells through metabolic and epigenetic reprograming. We show that in vitro treatment of CTLs and CAR T cells with pentanoate and butyrate increases the function of mTOR as a central cellular metabolic sensor, and inhibits class I histone deacetylase activity. This reprogramming results in elevated production of effector molecules such as CD25, IFN-γ and TNF-α, and significantly enhances the anti-tumor activity of antigen-specific CTLs and ROR1-targeting CAR T cells in syngeneic murine melanoma and pancreatic cancer models. Our data shed light onto microbial molecules that may be used for enhancing cellular anti-tumor immunity. Collectively, we identify pentanoate and butyrate as two SCFAs with therapeutic utility in the context of cellular cancer immunotherapy.}, language = {en} }
