  This study presents the important finding that lysosomal damage triggers inflammatory signaling through ubiquitination and the TAB-TAK1-IKK-NF-kB axis. The data obtained from the unbiased transcriptomic and proteomic analyses are convincing and provide invaluable information to the field. Although further experiments will be required to clarify how TAB2/3 are recruited after various types of lysosome damage, this work will be of interest to researchers in the fields of organelle biology and inflammation.

  This paper reports a large drug repurposing screen based on an in vitro culture platform to identify compounds that can kill Plasmodium hypnozoites. This valuable work adds to the current repertoire of anti-hypnozoites agents and uncovers targetable epigenetic pathways to enhance our understanding of this mysterious stage of the Plasmodium life cycle. The data presented here are based on solid methodology and represent a starting point for further investigation of epigenetic inhibitors to treat P. vivax infection. This paper will be of interest to Plasmodium researchers and more broadly to readers in the fields of host-pathogen interactions and drug development.

Physiological febrile heat stress increases cytoadhesion through increased protein trafficking of Plasmodium falciparum surface proteins into the red blood cell

  This important study provides compelling evidence that fever-like temperatures enhance the export of Plasmodium falciparum transmembrane proteins, including the cytoadherence protein PfEMP1 and the nutrient channel PSAC, to the red blood cell surface, thereby increasing cytoadhesion. Using rigorous and well-controlled experiments, the authors convincingly demonstrate that this effect results from accelerated protein trafficking rather than changes in protein production or parasite development. These findings significantly advance our understanding of parasite virulence mechanisms and offer insights into how febrile episodes may exacerbate malaria severity.

  This study provides valuable insights into microtubule remodeling during liver-stage Plasmodium berghei development, demonstrating that deletion of the alpha-tubulin C-terminal tail impairs parasite growth in mosquitoes and abolishes infection in HeLa cells. The work is technically ambitious, employing advanced microscopy, genetic mutants, and pharmacological approaches. However, key claims are only partially supported due to incomplete evidence linking tubulin modifications to microtubule dynamics and uncertain antibody-based PTM detection.

  This important study describes a non-canonical role for IκBα in regulating mouse embryonic stem cell pluripotency and differentiation, independent of the classical NF-κB pathway. The conclusions are convincingly supported through orthogonal approaches and separation of function mutants. The findings add new insight into pluripotency regulation in mouse cells.

  This important study introduces a new class of spectrally tunable, dye-based calcium sensors optimized for imaging in organelles with high calcium concentrations, such as the endoplasmic reticulum and mitochondria. The experimental evidence supporting the applicability of these sensors is convincing, with thorough validation in cultured cells and neurons. The work will be of high interest to researchers studying calcium signaling dynamics in subcellular compartments.

  Axon growth is essential to formation of neural connections. This manuscript presents a useful presentation of a new method for assessing the adhesion strength of axons with the use of a laser-induced shock wave. However, the strength of the evidence is incomplete as critical controls for calibration and time course are lacking.
