Precise control of wound healing depends on physician’s evaluation, experience. Physicians provide conditions and time for body to either heal itself, or to accept and heal around direct transplantations, and their practice relies a lot on passive recovery. Slow healing of recalcitrant wounds is a known persistent problem, with incomplete healing, scarring, and abnormal tissue regeneration. 23% of military blast and burn wounds do not close, affecting a patient’s bone, skin, nerves. 64% of military trauma have abnormal bone growth into soft tissue. While newer static approaches have demonstrated enhanced growth of non-regenerative tissue, they do not adapt to the changing state of wound, thus resulting in limited efficacy.

A groundbreaking method for the efficient isolation and preservation of high-purity small extracellular vesicles (sEVs - exosomes) from biofluids using a novel EXO-PEG-TR reagent.

Researchers at UCI and Harvard have engineered a new platform for diversifying antibody genes in yeast, eliminating a crucial bottleneck in making effective antibodies. This technology enables the rapid continuous directed evolution of affinity reagents for applications ranging from structural and cellular biology to diagnostics and immunotherapy.

This technology offers a significant improvement in the therapeutic application of type E botulinum neurotoxin (BoNT/E) by introducing rationally designed mutations into the receptor binding domain.

SUMO inhibitors offer a promising new therapy for protecting against cardiac rhythm disturbances and pump failure associated with heart attacks.

Existing RNA-targeting tools for sequence-specific manipulation include anti-sense oligos (ASOs), designer PUF proteins and CRISPR (Clustered Regularly Interspaced Short Palindromic Repeats)/Cas systems. However, there are significant limitations to each of the current tools. ASOs are usually not available for most RNA manipulations other than gene silencing. Designer proteins, such as PUF (Pumilio and FBF homology protein), possess low RNA recognition efficiency and it remains challenging to target RNA sequences >8-nucleotides (nt) in length. The bulky Cas protein (Cas13d: average 930 amino acids) leads to complication for transgene delivery and concerns of its immunogenicity due to its bacterial origin. Mutants of zinc finger(ZnF) proteins in ZRANB2 recognize a single-strand RNA containing a novel GGG motif with micromolar affinity, compared to the original motif GGU. These mutants serve as a foundation for RNA-binding ZnF designer protein engineering for in vivo RNA sequence-specific targeting.ZnFs are generally compact domains (~3kDa each) that have been successfully engineered for DNA recognition as modular arrays. A ZnF-based system has unique advantages, especially in a therapeutic context: (1) Broad application with the possibility to fuse with other effector domains; (2) High efficiency of RNA recognition (3 RNA bases recognized per 30-amino-acid ZnF) with a small size of protein. Only 4 ZnFs (~100 aa) is required for specific targeting in the transcriptome. (3) Humanized components without immunogenic concern.By engineering new sequence specificity of the ZRANB2 ZnF1, researchers from UC San Diego identified 13 mutants that altered their preferred RNA binding motif from GGU to GGG. They are N24R, N24H, N14D/N24R, N14D/N24H, N14R/N24R, N14R/N24H, N14H/N24R, N14H/N24H, N14Q/N24R, N14Q/N24H, N14E/N24R, N14S/N24R, N14E/N24H.

An innovative approach using tetracosapentaenoic acid to treat age-related eye disorders by replenishing critical lipids in the retina.

Although viral delivery of CRISPR genome editors is the most widely used method for in vivo cell editing, viral vectors can be immunogenic, carry the risk of vector genome integration and can induce off-target DNA damage due to continuous genome editor expression. Lipid-nanoparticle (LNP):mRNA complexes are non-virally derived vehicles for in vivo delivery that have provided for genome editing in the liver. However, developing LNP:mRNA complexes that can edit non-liver tissues remains a challenge.  UCB researchers have created new LNP compositions and methods for delivery that have increased efficiency for delivering a molecular payload such as CRISPR-Cas effector proteins, guide RNAs, and/ nucleic acids encoding same.
