Summary: Corneal opacification is the fourth most common cause of blindness globally. The standard treatment for serious corneal scarring is corneal transplantation, but there are limitations such as long-term graft survival and the lifelong use of immunosuppressants. Research is focused on finding new technologies to modulate wound healing and prevent corneal opacification.

Summary: This study found that Hyp-O-polysaccharides isolated from transgenic Arabidopsis suspension culture have similar structural features to AGPs isolated from tobacco. It also confirmed the presence of a previously identified β-1,6-linkage on the galactan backbone in AGP fusion glycoproteins expressed in tobacco. Furthermore, AGPs expressed in Arabidopsis suspension culture have differences in terminal-rhamnosyl residues and glucuronosylation compared to those expressed in tobacco suspension culture, suggesting the presence of distinct glycosyl transferases and minimum AG structures for type II AG functional features.

Summary: The acellular porcine corneal stroma (APCS) hydrogel demonstrated optimal light transmittance and gelation properties, retaining critical corneal ECM components. It showed higher porosity, faster nutrition diffusion, improved proliferation of corneal cells, and enhanced viability and infiltration. The APCS-gel also improved corneal epithelial stemness and wound healing in vitro and in vivo, making it a promising option for clinical applications.

Summary: This study evaluated the initial healing effects of PRP gel and PRF on deep corneal wounds. The results showed that PRP gel promoted vascular healing and myofibroblast production, contributing to corneal remodeling. However, the use of PRF was not recommended due to its potential complications during tissue healing.

Summary: Corneal wound healing involves communication between different cell types, which is partially mediated by exosomes. This study isolated exosomes released by different corneal cell types and found that they can accelerate wound healing. Additionally, exosomes alter the expression pattern of regulated genes. These findings are important for understanding the mechanisms of corneal wound repair and may lead to new therapeutic approaches.

Summary: This study investigates the role of dsRNA and its regulatory network in corneal wound healing. The results show that dsRNA activates IFN-I signaling, primarily IFN-beta, to promote corneal epithelial reconstruction, and identify MMP13 as a downstream effector in this process.

Summary: Inflammation plays a complex role in corneal wound healing. While acute inflammation is necessary to prevent infection, chronic or excessive inflammation can delay healing and worsen outcomes. Reductions in severe or chronic inflammation lead to better corneal clarity, thickness, and healing.

Summary: This study used quantitative proteomics to identify key factors involved in the differentiation-dependent protein profile changes in human corneal stromal cells. The differentiated fibroblasts and myofibroblasts expressed proteins related to cellular signaling pathways, SLIT-ROBO pathways, and extracellular matrix, indicating their potential role in corneal wound healing. The identified proteins such as profilin 1 and talin could potentially serve as targets for treating corneal fibrosis.

Summary: Hyperglycemia reduces NAD(+) biosynthesis in the cornea, leading to impaired epithelial wound healing in diabetic mice and patients. Replenishment of NAD(+) and its precursors can facilitate corneal wound healing and nerve regeneration in diabetic conditions, suggesting a novel therapeutic strategy for diabetic corneal complications.

Summary: This study investigates the role of NSUN2 in corneal epithelial wound healing (CEWH) and its underlying mechanisms. The expression of NSUN2 and RNA m5C level significantly increased during CEWH. NSUN2 knockdown delays CEWH and inhibits cell proliferation and migration, while NSUN2 overexpression enhances cell proliferation and migration. Mechanistically, NSUN2 increases the translation of UHRF1 mRNA through the binding of RNA m5C reader Aly/REF export factor, thereby modulating CEWH. This finding highlights the critical importance of this novel epitranscriptomic mechanism in controlling CEWH.

Summary: Recent evidence suggests that epithelial stem/progenitor cells in barrier tissues retain a memory of previous injuries, enabling faster restoration of the barrier after subsequent injuries. The corneal epithelium, the outermost layer of the cornea, also shows signs of inflammatory memory. Mice and ocular Sjogren's syndrome patients both exhibited accelerated corneal wound healing and reduced inflammation after subsequent injuries, indicating the presence of nonspecific inflammatory memory in the cornea.

Summary: This study aimed to optimize the transethosomal formulation of rosuvastatin for enhanced topical wound healing efficiency. The optimized formulation showed good encapsulation efficiency, stability, and improved wound healing effect, possibly due to the enhanced penetration of nanovesicles into the skin.

Summary: Aquaporins (AQPs) are transmembrane water channel proteins that regulate corneal hydration and transparency. They play a crucial role in keratocyte function, inflammation, edema, angiogenesis, and the wound healing process in the cornea. Deficiency of AQPs can lead to abnormal wound healing and impaired osmolar homeostasis. This review discusses the role of AQPs in corneal homeostasis, wound repair, and their potential as therapeutic targets for corneal injuries.

Summary: This study explored the potential of a combination of in situ gelling systems and a loaded drug self-assembling nanomicellar carrier as a new Ocular Drug Delivery System for Cyclosporine-A. By optimizing the physical-chemical characterization of the nanomicelles and incorporating them into ion-sensitive polymeric dispersions, the system showed improved ocular bioavailability of CyA and reduced cytotoxicity. This new approach prevented CyA transcorneal permeation and extended its resident time in the precorneal area, showing promise for future ocular drug delivery systems.

Summary: Hyaluronic acid is a naturally occurring polysaccharide with various molecular functions. HA-3, obtained by functionalizing HA with the metalloproteinase inhibitor 3 (MMPI), demonstrates increased resistance to degradation by hyaluronidase and MMP inhibition properties. HA-3 has the potential to prevent dehydration of human corneal epithelial cells and enhance the development of more effective DES treatments and broader applications of HA in human diseases.

Summary: This study compares the protein profile of pig claustrum (CLA), putamen (PU), and insula (IN) using a comparative proteomic approach. The results show greater differences in protein spot expression between CLA and PU compared to CLA and IN. Deregulated proteins in CLA are associated with neurodegenerative and psychiatric disorders in humans. Analysis suggests the involvement of these anatomical structures in neurodegenerative diseases. Overall, this study provides insights into the proteomic analysis of pig CLA and its potential involvement in neurodegenerative and psychiatric disorders in humans.

Summary: This study evaluated the viability and mobility of rooster sperm, as well as the occurrence of normal cells and sperm injuries, in post-thawed pelleted sperm. Different pelleting protocols were compared, and it was found that the protocols using 6% DMA showed the highest values of thawed sperm mobility. The most favorable thawing methods were using the hot-plate at 60 degrees C or the water-bath at 50 degrees C. The best sperm quality parameters were achieved with a 1:2 dilution rate, a 30-min equilibration time at 4 degrees C, 6% DMA, and thawing 80 muL pellets using the water-bath at 50 degrees C or the hot-plate at 60 degrees C. Despite the damage caused by the freezing-thawing methodology, the survival rate of normal sperm cells reached 39%, with 32% recovered mobility compared to fresh sperm samples.
