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.

Lipid Nanoparticles (LNPs) are a leading platform for nucleic acid delivery, widely used in therapeutics and vaccine development. However, the process of optimizing new LNP formulations has been significantly hindered by labor-intensive and costly screening methods, which require individual injections into animal models. Given the vast array of potential lipid compositions and formulation variables, these constraints severely impede the efficiency of research and development.To overcome these challenges, UC Berkeley researchers have developed a novel approach for identifying and characterizing functional nucleic acid delivery vehicles. This innovative method leverages circular RNA barcoding technology, enabling a more efficient screening process. Instead of relying on conventional cell sorting techniques, which restrict screening to specific organs and host species, this breakthrough allows direct detection of barcoded nucleic acids within circular RNAs in treated cells. By analyzing the barcodes detected, researchers can accurately determine which lipid compositions and formulations successfully delivered RNA molecules.  This technology represents a significant advancement in LNP research, offering a scalable, cost-effective solution that enhances the precision and scope of nucleic acid delivery screening.

      Biologics are antibodies produced by genetically engineered cells and are widely used in therapeutic applications. Examples include pembrolizumab (Keytruda) and atezolizumab (Tecentriq), both employed in cancer immunotherapy as checkpoint inhibitors to restore T- cell immune responses against tumor cells. These biologics are produced by engineered cells in bioreactors in a process that is highly sensitive to the bioreactor environment, making it essential to integrate process analytical technologies (PAT) for closed-loop, real-time adjustments. Recent trends have focused on leveraging integrated circuit (IC) solutions for system miniaturization and enhanced functionality, for example enabling a single IC that monitors O2, pH, oxidation-reduction potential (ORP), temperature, and glucose levels. However, no current technology can directly and continuously quantify the concentration and quality of the produced biologics in real-time within the bioreactor. Such critical measurements still rely on off-line methods such as immunoassays and mass spectrometry, which are time-consuming and not suitable for real- time process control.       UC Berkeley researchers have developed a microsystem for real-time, in-vivo monitoring of antibody therapeutics using structure-switching aptamers by employing an integrator-based readout front-end. This approach effectively addresses the challenge of a 100× reduction in signal levels compared to the measurement of small-molecule drugs in prior works. The microsystem is also uniquely suited to the emerging paradigm of “living pharmacies.” In living pharmacies, drug-producing cells will be hosted on implantable devices, and real-time monitoring of drug production/diffusion rates based on an individual’s pharmokinetics will be crucial.

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.

mRNA-based cancer therapies include vaccination via mRNA delivery of tumor neoantigens, delivery of mRNA encoding for immune checkpoint and other protein therapeutics, and induced expression of anticancer surface proteins such as CAR expression in T cells. Success requires transfection of a critical number of immune cells together with appropriate immune-stimulation to effectively drive anti-tumor responses. UC Berkeley researchers have developed an adjuvant-assisted mRNA LNP delivery method that uses mRNA LNP and adjuvant to enhance delivery of nucleic acids to immune cells in vivo and stimulate immune cells. They demonstrated the use of this system to reduce mRNA reporter protein expression in the liver and enhance protein expression in the spleen in mice and also demonstrated this system can be used to genetically engineer T cells by delivering a Cre-recombinase mRNA construct- transfection and editing of approximately 4% of T cells is achieved in vivo. The immune response is superior in our system compared to current, commercial lipid nanoparticle delivery technologies.

The rippled sheet was proposed by Pauling and Corey as a structural class in 1953. Following approximately a half century of only minimal activity in the field, the experimental foundation began to emerge, with some of the key papers published over the course of the last decade. Researchers at UC Santa Cruz have explored the structure of and have discovered ways to form new beta rippled sheets. 

A primary reason behind the lack of progress in heart therapeutics is the inability to use phenotypic human tissue-level approaches to discover novel therapies. In recent years, there have been significant advances in the development microphysiological systems (MPS), which recapitulate organ-level and even organism-level functions.   MPS are quickly becoming representative of the future of disease modeling and drug screening, therefore paving the way for complex in vitro models to dominate the preclinical drug discovery landscape. However, there has yet to be an effective LNP formulation for therapeutic mRNA delivery to the heart. Therefore, despite progress in this area, one of the remaining challenges is to develop a LNP formulation capable of diffusing within human cardiac muscle, transfecting cardiomyocytes, and escaping the endo-lysosome before degradation more efficiently than current strategies. UC Berkeley researchers and others have developed compositions and methods using lipid nanoparticles for delivery of a payload (e.g., messenger RNA (mRNA)) to the heart, for delivery of mRNA for transfection of cells and methods of treatment.

Researchers from UC San Diego have invented a new form of materials, polymer-integrated crystals (PIX), which combine the structural order of protein crystals with the dynamic, stimuli-responsive properties of synthetic polymers. The inventors have shown that the crystallinity, flexibility, and chemical tunability of PIX can be exploited to encapsulate guest proteins with high loading efficiencies. And, the electrostatic host-guest interactions enable reversible, pH-controlled uptake/release of guest proteins as well as the mutual stabilization of the host and the guest, thus creating a uniquely synergistic platform toward the development of functional biomaterials and the controlled delivery of biological macromolecules.
