  The authors studied the mechanisms by which dead cells are removed from the wounded skin in a process called efferocytosis. By analyzing different cell populations in the skin, the authors find that proteins involved in mediating the cell death and marking the cells as undergoing this process are elevated during distinct times in the wound healing program. Interestingly, these same proteins are elevated even higher in diabetic wounds. Finally the authors demonstrate that blocking the process of efferocytosis alters the wound healing program, thus illustrating its importance in effective wound repair.

  This study presents important findings on the regulation of the phosphate export cycle and identify the phosphatase Sit4 as a crucial player in regulation of the inner membrane potential of mitochondria. Whereas some of the data are convincing, the analyses will profit from deeper insights concerning metabolism alterations (carbon sources, amino acids). The major strength however is a new insight on how the cells use alternative ways for maintaining a critical mitochondrial inner membrane potential, and therefore this study is interesting to the broad audience with interests spanning from bioenergetics, metabolism and organellar and cell biology.

  This is an important study highlighting a distinct role of WASP dependent actin foci in B cell antigen receptor signalling. The evidence supporting the conclusions is compelling. The proposal of higher molecular density in B cell receptor clustering leading to kinase exclusion and attenuated signalling is provocative as it contrasts with models for other antigen receptors.

  This important study describes the coordinated regulation of cellular size and protein translation in response to chronic stress as an adaptive mechanism, termed the 'rewiring stress response' regulated by the heat shock response. The evidence supporting this conclusion is solid, utilizing diverse methods to monitor and manipulate cell size and evaluate stress resistance. The study could be strengthened by the inclusion of more experiments focused on defining the mechanistic basis of this coordination and broadening the scope of the specific role of the 'rewiring stress response' across different chronic cellular stresses. This work will be of broad interest to researchers interested in diverse fields including cellular proteostasis, stress-responsive signaling, and aging and senescence.

  This valuable study is focused on the requirement of the photoreceptor-specific tetraspanins, ROM1 and PRPH2, for the formation of light-sensitive membrane discs. The evidence supporting the claim that deficiency in one of the proteins can be compensated by the other is convincing, with both established and advanced techniques yielding results that will be of interest to those studying photoreceptor development and membrane curvature.
