TL;DR: Direct evidence is provided that venetoclax kills CLL cells in a TP53-independent fashion by inhibition of BCL2 in patients and support further assessment of BH3 profiling as a predictive biomarker for this drug.

TL;DR: It is found that mice derived from the C57BL/6 (B6) (H‐2b) background can develop CIA with high incidence, sustained severity by using an immunization procedure modified for optimum response in DBA/1 (D1) ( H‐2q) mice, and that CIA can be directly applied to gene knockout mice generated from B6 embryonic stem cells without need for backcross onto the D1 background.
Abstract: Collagen-induced arthritis (CIA) is a widely used model of rheumatoid arthritis (RA) and has been important for understanding autoimmunity. CIA is purportedly restricted to mice bearing the MHC class II H-2q or H-2r haplotypes. In this study, we re-examined established concepts regarding susceptibility to CIA. We found mice derived from the C57BU6 (B6) (H-2b) background can develop CIA with high incidence (60-70%), and sustained severity by using an immunization procedure modified for optimum response in DBA/1 (D1) (H-2q) mice. Clinically and histologically the B6 disease resembles that of D1 mice and is dependent on immunization with type II collagen, as well as on B and CD4+ T cells. In contrast, 129/Sv mice, which share H-2b, are resistant to CIA. We conclude that susceptibility to CIA may reflect immunization conditions and/or important contributions from non-MHC genes, revealed by different immunization protocols. A practical outcome is that CIA can be directly applied to gene knockout mice generated from B6 embryonic stem cells without need for backcross onto the D1 background. This model may lead to improved understanding of autoimmunity in CIA and RA and may provide a platform for analysis of the contribution of non-MHC genes to CIA.

TL;DR: By treating BRCA1-mutant breast cancers with cisplatin to increase their mutational load and then combining drugs targeting two different immune checkpoint inhibitors, the authors achieved promising results in mouse models, suggesting that a similar approach may also work for patients.
Abstract: Immune checkpoint inhibitors have emerged as a potent new class of anticancer therapy. They have changed the treatment landscape for a range of tumors, particularly those with a high mutational load. To date, however, modest results have been observed in breast cancer, where tumors are rarely hypermutated. Because BRCA1-associated tumors frequently exhibit a triple-negative phenotype with extensive lymphocyte infiltration, we explored their mutational load, immune profile, and response to checkpoint inhibition in a Brca1-deficient tumor model. BRCA1-mutated triple-negative breast cancers (TNBCs) exhibited an increased somatic mutational load and greater numbers of tumor-infiltrating lymphocytes, with increased expression of immunomodulatory genes including PDCD1 (PD-1) and CTLA4, when compared to TNBCs from BRCA1-wild-type patients. Cisplatin treatment combined with dual anti-programmed death-1 and anti-cytotoxic T lymphocyte-associated antigen 4 therapy substantially augmented antitumor immunity in Brca1-deficient mice, resulting in an avid systemic and intratumoral immune response. This response involved enhanced dendritic cell activation, reduced suppressive FOXP3+ regulatory T cells, and concomitant increase in the activation of tumor-infiltrating cytotoxic CD8+ and CD4+ T cells, characterized by the induction of polyfunctional cytokine-producing T cells. Dual (but not single) checkpoint blockade together with cisplatin profoundly attenuated the growth of Brca1-deficient tumors in vivo and improved survival. These findings provide a rationale for clinical studies of combined immune checkpoint blockade in BRCA1-associated TNBC.

TL;DR: It is reported that the production of subsets of antigen-presenting dendritic cells (DCs) is also defective and points to an essential role for the Ikaros gene family in the development of all DCs.

TL;DR: Tlymphocytes develop within the thymus, where they are positively selected for self-restriction and purged of cells exhibiting strong reactivity to self-antigens presented within this microenvironment.
Abstract: Tlymphocytes develop within the thymus, where they are positively selected for self-restriction and purged of cells exhibiting strong reactivity to self-antigens presented within this microenvironment. Mature lymphocytes then enter the peripheral lymphoid pool, where they recirculate between the
