Abstract
T regulatory type 1 (Tr1) cells, which are defined by their regulatory function, lack of Foxp3, and high expression of IL-10, CD49b, and LAG-3, are known to be able to suppress Th1 and Th17 in the intestine. Th1 and Th17 cells are also the main drivers of crescentic glomerulonephritis (GN), the most severe form of renal autoimmune disease. However, whether Tr1 cells emerge in renal inflammation and, moreover, whether they exhibit regulatory function during GN have not been thoroughly investigated yet. To address these questions, we used a mouse model of experimental crescentic GN and double Foxp3mRFP IL-10eGFP reporter mice. We found that Foxp3neg IL-10-producing CD4+ T cells infiltrate the kidneys during GN progression. Using single-cell RNA sequencing, we could show that these cells express the core transcriptional factors characteristic of Tr1 cells. In line with this, Tr1 cells showed a strong suppressive activity ex vivo and were protective in experimental crescentic GN in vivo. Finally, we could also identify Tr1 cells in the kidneys of patients with antineutrophil cytoplasmic autoantibody-associated GN and define their transcriptional profile. Tr1 cells are currently used in several immune-mediated inflammatory diseases, such as T-cell therapy. Thus, our study provides proof of concept for Tr1 cell-based therapies in experimental GN.

Abstract
Abstract
Seventy percent of breast cancers are estrogen receptor (ER) positive and, while the majority of these patients initially respond to hormone therapy, approximately 20-30% will become therapy refractory. Recent data suggest activating-mutations in the estrogen receptor gene (ESR1) ligand binding domain (LBD), which are acquired during anti-estrogen treatment and rarely found in primary untreated ER+ breast cancer, are associated with resistance. Some researchers propose that ESR1 mutations are a prognostic and predictive marker, but more studies are needed to assess the clinical utility of the ESR1 mutations. However, current ESR1 mutation detection methods, that is, next generation sequencing and digital PCR, are very labor-intensive, lengthy, and expensive and require special training.
To aid research on the diagnostic potential of ESR1 mutations, we developed a prototype allele-specific qPCR assay for the detection of 18 recurrent mutations in the ESR1 LBD. The test is suitable for DNA obtained from FFPE tissue as well cfDNA from plasma. It is sensitive, yet simple, robust and results can be obtained in less than 8 hours. Herein, we demonstrate the analytical performance of our ESR1 mutation detection assay using contrived samples. We are also planning to test clinical FFPET and plasma samples in the future.
