A distinct set of channels and transporters regulates the ion fluxes across the lysosomal membrane. Malfunctioning of these transport proteins and the resulting ionic imbalance is involved in various human diseases, such as lysosomal storage disorders, cancer, as well as metabolic and neurodegenerative diseases. As a consequence, these proteins have stimulated strong interest for their suitability as possible drug targets. A detailed functional characterization of many lysosomal channels and transporters is lacking, mainly due to technical difficulties in applying the standard patch-clamp technique to these small intracellular compartments. In this review, we focus on current methods used to unravel the functional properties of lysosomal ion channels and transporters, stressing their advantages and disadvantages and evaluating their fields of applicability.

The hallmarks of mechanosensitive ion channels have been observed for half a century in various cell lines, although their mechanisms and molecular identities remained unknown until recently. Identification of the bona fide mammalian mechanosensory Piezo channels resulted in an explosion of research exploring the translation of mechanical cues into biochemical signals and dynamic cell morphology responses. One of the Piezo isoforms - Piezo1 - is integral in the erythrocyte (red blood cell; RBC) membrane.

Ion channels are integral membrane proteins which facilitate rapid transport of small ions into and out of the cell and between organelles and cytosol. Cytolytic lymphocytes including natural killer (NK) cells principally kill virus-infected and cancer cells by releasing cytolytic granules within the immunological synapse, formed between target and effector cells. This process strongly depends on Ca2+ signaling, which in human NK cells is controlled by the phospholipase C (PLCγ)/inositol-1,4,5-triphospate receptor (IP3R)/calcium release-activated calcium channel (CRAC) axis.

In recent years, light-controlled ion transport systems have attracted widespread attention, however, the use of photoresponsive materials suffers from rapid carrier recombination, thermal field limitations, and narrow spectral response, which significantly restricts their performance enhancement in osmotic energy conversion. This study innovatively couples "blue energy" (osmotic energy) with "green energy" (solar energy), assembling graphene oxide/molybdenum disulfide/sulfonated cellulose nanocrystal (GO/ MoS/CNC) ion-channel membranes. Under solar irradiation, the energy level difference between MoS and GO effectively suppresses the recombination of photogenerated carriers, generating more active electrons and significantly enhancing the carrier density, thereby improving the current flux and ion selectivity.

Pufferfish exhibit the smallest vertebrate genomes, making them ideal models for investigating evolutionary patterns and processes that affect genome size. While the Takifugu rubripes genome was fully sequenced two decades ago, key evolutionary drivers remain elusive. We sequenced 10 pufferfish genomes and generated 35 transcriptomes and 13 methylomes to understand genomic evolutionary mechanisms.

Artificial porous polymer coatings are promising for alleviating the side reactions and dendrite growth on Zn anodes. Nevertheless, the low ion transport ability constrains their application under harsh conditions such as thin Zn foil, high current density, and high depth of discharge (DOD). Herein, a 2D active filler is introduced to optimize the Zn migration in porous polymer coating.
