| Open AccessNon-invasive modulation of meningeal lymphatics ameliorates ageing and Alzheimer’s disease-associated pathology and cognition in mice
Meningeal lymphatic vessels have been associated with amyloid beta clearance, which is considered as a modulation target for Alzheimer’s disease (AD) treatment. Here, the authors show that transcranial light treatment can enhance meningeal lymphatic drainage in aged and AD model mice and improve AD-associated pathology and cognitive function.

| Open AccessPAF1c links S-phase progression to immune evasion and MYC function in pancreatic carcinoma
MYC drives S-phase progression and immune invasion in pancreatic ductal adenocarcinoma (PDAC), but the underlying mechanisms are not fully understood. Here, the authors show that the transcription elongation complex PAF1c controls the competition of different gene sets for RNA polymerase and elongation factors to regulate these MYC-associated mechanisms in PDAC.

| Open AccessCell softness renders cytotoxic T lymphocytes and T leukemic cells resistant to perforin-mediated killing
Cell softness protects cytotoxic T lymphocytes (CTL) from autolysis by own soluble factors such as perforin secreted for killing target cells. Here the authors show that softness can be induced by YAP activation, and that T leukemic cells are more sensitive to YAP inhibition than CTLs, thereby hinting YAP inhibitors as a potential therapy for T leukemia.

Treatment with the clinical stage TGF-β inhibitor galunisertib promotes latency reversal of HIV/SIV. Here, using a treatment regimen similar to the one tested in clinical trials, the authors show how galunisertib affects immune cell function, increases SIV reactivation, and reduces the viral reservoir in macaques.

| Open AccessGene-expression-based T-Cell-to-Stroma Enrichment (TSE) score predicts response to immune checkpoint inhibitors in urothelial cancer
Immune checkpoint inhibitor treatment improves overall survival in metastatic urothelial cancer, but response of individual patients varies significantly. Authors here perform whole-genome DNA and bulk RNA sequencing on samples from metastatic tumours and based on these data, they set up a single metric, T cell-to-stroma enrichment (TSE) score, that reflects the relative abundance of T cells versus stromal cells and their products, accurately predicting therapeutic outcome.

| Open AccessEpigenetic regulation of CD38/CD48 by KDM6A mediates NK cell response in multiple myeloma
The anti-CD38 monoclonal antibody Daratumumab is approved for the treatment of multiple myeloma but efficiency is curtailed by secondary resistance. Here authors show that the antibody-dependent cellular cytotoxicity, which is the main mechanism of action for Daratumumab, is regulated by KDM6A via Histone H3 K27 methylation of CD38 and CD48, downregulation of which leads to drug resistance.

| Open AccessMotility and tumor infiltration are key aspects of invariant natural killer T cell anti-tumor function
Invariant natural killer T (iNKT) cells are important contributors to anti-tumour immunity, but they often become dysfunctional in cancers. Here authors show that inhibited iNKT intra-tumour motility and iNKT cell exclusion from tumours by macrophages both contribute to their diminished function in cancer, and by therapeutic interference with the respective motility and iNKT-macrophage interaction pathways, their function can be restored.

Invariant natural killer T (iNKT) cells recognize abnormal cells, but their T cell receptor is not variable and kill cancerous or infected target cells without MHC I restriction. Here, the authors show that in a clinical trial, donor-unrestricted allogeneic iNKT cells could be safely administered to human COVID-19 patients suffering from acute respiratory distress syndrome and trigger an anti-inflammatory response.

Gain-of-function mutations in NLRP3 result in Cryopyrin-Associated Periodic Syndrome in human patients. Here authors show that although these NLRP3 variants are constitutively active, they preserve their responsiveness to external pro-inflammatory stimuli, and they interfere with the immune-metabolic inflammatory pathways in monocytes.
