Project description:We have found many differences between B1a cells from p40-/-CD25-/- mice and control mice. To better understand the whole change of transcriptions profile between B1a cells in PC of p40-/-CD25-/- mice and control mice. By using flow cytometry and high-resolution microarrays, we have studied qualitative and quantitative characteristics of B1a cells of p40-/-CD25-/- mice and control mice.

Project description:Sle2c1 is an NZM2410-derived lupus susceptibility locus that induces an expansion of the B1a cell compartment. B1a cells have a repertoire enriched for autoreactivity, and an expansion of this B cell subset occurs in several mouse models of lupus. Here we showed that expression of Sle2c1 enhances NZB cellular phenotypes that have been associated with autoimmune pathogenesis. A combination of genetic mapping and candidate gene analysis presents Cdkn2c, a gene encoding for cyclin kinase inhibitor p18INK4c (p18), as the top candidate gene for inducing the Slec2c1 associated expansion of B1a cells. A novel SNP in the Cdkn2c promoter is associated with a significantly reduced Cdkn2c expression in the splenic B cells and B1a cells from Sle2c1-carrying mice, which leads to defective G1 cell cycle arrest in splenic B cells and increased proliferation of Pc B1a cells. As cell cycle is differentially regulated in B1a and B2 cells, these results suggest that Cdkn2c play a critical role in B1a cell self renewal, and that its impaired expression leads to an accumulation of these cells with high autoreactive potential. Total RNA from peritoneal cavity B cells (B1a) and splenic B cells (Bs) was isolated, with 4 biological replicates each. Gene expression data from C57BL/6 mice were compared with data from B6.Sle2c1 mice.

Project description:Amyloidogenic peptides are therapeutic in EAE, reducing systemic levels of IL6, TNF, and INFg. The fibrils are bound and endocytosed in peritoneal MFs and B1a cells. Differential gene expression was used to further understand the process. Groups of three female C57BL/6 mice were injected with 10ug of Tau 623-628, Amylin 28-33, LPS, or PBS. 30-40 minutes post injection, the peritoneal cavity was lavaged, CD11b high (MFs) and CD5+CD19+ (B1a lymphocytes) were purified by flow cytometry directly into Trizol. RNA was extracted from the aqueous phase using the Qiagen RNeasy microkits. RNA quality was assessed using the Agilent 2100 bioanalyzer and the RNA 6000 nano reagents kit. One color microarray, Agilent-028005 SurePrint G3 Mouse GE 8x60K Microarray, was performed at the human immune monitoring center. All samples were processed and run at the same time.

Project description:In this study, we analyzed the submandibular glands of P40-/-CD25+/- (control mice) and P40-/-CD25-/- (SS mice) after PD-1-targeted CAR-T cells or control T cells treatment using RNA-Seq. We found that the transcription of inflammatory genes was down-regulated and the transcription of tissue repair genes was up-regulated in the submandibular glands of SS mice after PD-1-targeted CAR-T cells treatment. In addition, PD-1+Tigit+CD8+ T cells in the submandibular gland draining lymph nodes of SS mice showed transcription characteristics of tissue resident memory precursors.

Project description:Introgressed variants from other species can be an important source of genetic variation because they may arise rapidly, can include multiple mutations on a single haplotype, and have often been pretested by selection in the species of origin. Although introgressed alleles are generally deleterious, several studies have reported introgression as the source of adaptive alleles-including the rodenticide-resistant variant of Vkorc1 that introgressed from Mus spretus into European populations of Mus musculus domesticus. Here, we conducted bidirectional genome scans to characterize introgressed regions into one wild population of M. spretus from Spain and three wild populations of M. m. domesticus from France, Germany, and Iran. Despite the fact that these species show considerable intrinsic postzygotic reproductive isolation, introgression was observed in all individuals, including in the M. musculus reference genome (GRCm38). Mus spretus individuals had a greater proportion of introgression compared with M. m. domesticus, and within M. m. domesticus, the proportion of introgression decreased with geographic distance from the area of sympatry. Introgression was observed on all autosomes for both species, but not on the X-chromosome in M. m. domesticus, consistent with known X-linked hybrid sterility and inviability genes that have been mapped to the M. spretus X-chromosome. Tract lengths were generally short with a few outliers of up to 2.7 Mb. Interestingly, the longest introgressed tracts were in olfactory receptor regions, and introgressed tracts were significantly enriched for olfactory receptor genes in both species, suggesting that introgression may be a source of functional novelty even between species with high barriers to gene flow.

Project description:Translational research is commonly performed in the C57B6/J mouse strain, chosen for its genetic homogeneity and phenotypic uniformity. Here, we evaluate the suitability of the white-footed deer mouse (Peromyscus leucopus) as a model organism for aging research, offering a comparative analysis against C57B6/J and diversity outbred (DO) Mus musculus strains. Our study includes comparisons of body composition, skeletal muscle function, and cardiovascular parameters, shedding light on potential applications and limitations of P. leucopus in aging studies. Notably, P. leucopus exhibits distinct body composition characteristics, emphasizing reduced muscle force exertion and a unique metabolism, particularly in fat mass. Cardiovascular assessments showed changes in arterial stiffness, challenging conventional assumptions and highlighting the need for a nuanced interpretation of aging-related phenotypes. Our study also highlights inherent challenges associated with maintaining and phenotyping P. leucopus cohorts. Behavioral considerations, including anxiety-induced responses during handling and phenotyping assessment, pose obstacles in acquiring meaningful data. Moreover, the unique anatomy of P. leucopus necessitates careful adaptation of protocols designed for Mus musculus. While showcasing potential benefits, further extensive analyses across broader age ranges and larger cohorts are necessary to establish the reliability of P. leucopus as a robust and translatable model for aging studies.

Project description:Mouse peritoneal B1a cells were classified into two groups based upon the expression level of PC1. One is PC1 high group and the other is PC1 low. To evaluate gene expression patterns that distinguished PC1 high expressing B1a cells from PC1 low expressing B1a cells, we used Affymetrix GeneChip® Mouse gene 1.0 ST Array.
