  This valuable study investigates the immune system's role in pre-eclampsia. The authors map the immune cell landscape of the human placenta and find an increase in macrophages and Th17 cells in patients with pre-eclampsia. Following mouse studies, the authors suggest that the IGF1-IGF1R pathway might play a role in how macrophages influence T cells, potentially driving the pathology of pre-eclampsia. There is convincing evidence in this study that will be of interest to immunologists and developmental biologists.

  This study describes the impact of mycobacterial genetic diversity on host-infection phenotypes by assessing the effect of different M. tuberculosis lineages on granulomatous inflammation using a 3D in vitro granuloma model. Despite being descriptive and showing mostly correlative relationships, the findings are useful and provide some solid support regarding the functional impact of M. tuberculosis's natural diversity on host-pathogen interactions. The study will interest researchers working on mycobacteria and motivate future studies to understand how genetic diversity influences virulence and immunity outcomes.

  The authors aim to elucidate the mechanism by which pyroptosis (through the formation of Gasdermin D (GSDMD) pores in the plasma membrane) contributes to increased release of procoagulant Tissue Factor-containing microvesicles. The data offers solid mechanistic insights as to the interplay between pyroptosis and microvesicle release with NINJ1. The study provides useful insights into the potential of targeting Ninj1 as a therapeutic strategy.

SIV-specific neutralizing antibody induction following selection of a PI3K drive-attenuated nef variant

1. Hiroyuki Yamamoto

• Curated by eLife

  eLife Assessment

  Yamamoto and Matano provide convincing evidence that a G63E/R CD8+ T-cell escape mutation in the accessory viral protein Nef promote the induction of neutralizing antibody (nAb) responses in rhesus macaques infected with SIVmac239, which is usually largely resistant to neutralization. Functional analyses support that this mutation specifically impairs Nef`s ability to stimulate PI3K/Akt/mTORC2 signalling. This important study suggests that the accessory viral protein Nef impairs B cell function and effective humoral immune responses and is of interest for researchers and physicians interested in HIV/AIDS and vaccine development.

  The manuscript addresses the 3D chromatin architecture in monocytes from patients with alcohol-associated hepatitis and its relationship to enhanced transcription of innate immune genes. While the concept and methodological approach are appealing, the evidence is incomplete as a result of insufficient sample sizes as well as other significant analytical concerns.

  This study on mouse Ly49 receptors expressed on natural killer (NK) cells shows that Ly49A, in the presence of the corresponding MHC Class I allele, can lead to NK cell licensing, thereby providing valuable insights into the mechanisms of NK cell modulation by Ly49 receptors. The work may have significant implications for studies of human Killer-cell immunoglobulin-like receptors (KIR) expressing and other NK cells. Overall, the study was well-developed with convincing evidence.

  This study provides useful information by identifying the cell type (macrophages) in synovial tissues involved in the pathogenesis of post-traumatic osteoarthritis (OA) and clarifying distinct transcriptomic signatures that may be a good therapeutic target for OA. However, the analysis performed so far is incomplete, with a main weakness being the lack of data to confirm the authors' speculation about the underlying mechanisms.
