Researchers at the University of California, Davis have developed a technology that introduces vaccines that express macrophage-suppressing molecules to significantly enhance inflammatory T-cell functions for improved immune responses.

Researchers at the University of California, Davis have engineered dominant negative CD40L mutant polypeptides that inhibit CD40/CD40L-mediated signaling, offering therapeutic potential for inflammatory, immune disorders, and cancer with improved safety profiles.

Researchers at the University of California, Davis, have developed a process for isolating anti-inflammatory lipids for treating autoimmune and inflammatory diseases.

Researchers at the University of California, Davis, have developed a novel imaging system that improves the diagnostic accuracy of PET imaging. The system combines machine learning and computed tomography (CT) imaging to reduce noise and enhance resolution. This novel technique can integrate with commercial PET imaging systems, improving diagnostic accuracy and facilitating superior treatment of various diseases.

      Current clinical practice for detecting low-concentration molecular biomarkers requires sending samples to centralized labs, leading to high costs and delays. Successful point-of-care (POC) diagnostic technology exist, such as the paper-based lateral-flow assay (LFA) used for pregnancy tests and SARS-CoV-2 rapid antigen tests, or miniaturized instruments such as the Abbot i-Stat Alinity. However, the former provides binary results or limited quantitative accuracy, and the latter is too expensive for in-home deployment. A promising approach for POC diagnostics, offering tailored circuit optimization, multiplexed detection, and significant cost and size reductions, is millimeter-sized CMOS integrated circuits coupled with microfluidics. Recent demonstrations include protein, DNA/RNA, and cell detection. The current complexity of system packaging (e.g., wire/flip-chip bonding) makes integrating microfluidics with more sophisticated functions challenging, and often-required syringe pumps and tubing are operationally unfriendly, limiting current approaches.       UC Berkeley researchers have developed a fully integrated, multi-mode POC device that requires single-step assembly and operates autonomously. Drawing inspiration from RFID technology and implantables, they have introduced inductively-coupled wireless powering and communication functionality into a CMOS bio-analyzer. With the chip being fully wireless, the die can be easily integrated into a substrate carrier, achieving a completely flat surface that allows for seamless bonding with the microfluidic module. In the final product, the device will be sealed in a pouch inside a vacuum desiccator. The user tears the pouch, adds a drop of sample, and the system automatically begins operation. The operation window can last up to 40 minutes, making the process insensitive to time delays. The present CMOS bio-analyzer integrates pH-sensing and amperometric readout circuits for both proton-based and redox-based immunoassays.

Inflatable pouches are attractive as actuators and structural links in soft robots due to their low deflated profile and high deformation ratio. Particularly compelling for minimally invasive surgery, deflated robots/actuators may be deployed in small form factors and maneuver delicately in tight spaces once inflated. However, current fabrication methods do not readily scale for production of actuators with less than 1 mm feature sizes; they often require precision handling of separator films; and/or there are limited multilayer integration capabilities. Fully miniaturized, high degree-of-freedom surgical pouch robots and actuators have not yet been realized.To overcome these challenges, UC Berkeley researchers have developed a rapid, monolithic, and scalable manufacturing method for fabricating thin-film-based pneumatic pouch soft robots. Small features (less than 0.3 mm) can be patterned at high speeds and using commercially available manufacturing tools while maintaining film planarity. Resulting robots can have complex, multilayer structures including single- and bi-directional joint actuators, structural links, integrated in-plane air channels, through-holes for interlayer connectivity, and air inlets to a supply manifold—from a single integrated processing step. Researchers have demonstrated a miniature four finger hand which can dexterously manipulate a cube (8 degrees of freedom), as well as an 10 degree-of-freedom planar arm with a gripper which can maneuver around obstacles. Entire pouch robot structures can have un-inflated thickness of less than 300 um and be inherently soft, allowing the robots to be used in tight spaces with fragile tissues for surgical applications.

Lipoxygenases (LOX) are enzymes that catalyze the peroxidation of certain fatty acids. The cell membrane is mostly made of lipids (which include fatty acids), and peroxidation can cause damage to the cell membrane. The human genome contains six functional LOX genes that encode for six LOX enzyme variants, or isozymes. The role that each LOX isozyme plays in health and disease varies greatly, spanning issues such as asthma, diabetes, and stroke. LOX enzymes are extremely difficult to target due to high hydrophobicity. Potential leads are often ineffective because they are either not readily soluble or not selective for a particular LOX enzyme.  Studies have implicated human epithelial 15-lipoxygenase-2 (h15-LOX-2, ALOX15B) in various diseases. h15-LOX-2 is highly expressed in atherosclerotic plaques and is linked to the progression of macrophages to foam cells, which are present in atherosclerotic plaques. h15-LOX-2 mRNA levels are also highly elevated in human macrophages isolated from carotid atherosclerotic lesions in symptomatic patients. Children with cystic fibrosis had reduced levels of h15-LOX-2, which affects the lipoxin A4 to leukotriene B4 ratio. Furthermore, the interactions of h15-LOX-2 and PEBP1 changes the substrate specificity of h15-LOX-2 from free polyunsaturated fatty acids (PUFA) to PUFA-phosphatidylethanolamines (PE), leading to the generation of hydroperoxyeicosatetraenoic acid (HpETE) esterified into PE (HpETE-PE). Accumulation of these hydroperoxyl membrane phospholipids has been shown to cause ferroptotic cell death, which implicates h15-LOX-2 in neurodegenerative diseases such as Alzheimer’s, Parkinson’s, and Huntington’s diseases.  

Researchers at UC Irvine have identified and tested a molecular target that regulates T cell function during chronic viral infection and cancer. The molecular target is one of the high mobility group proteins (HMGB2). HMGB2 is a DNA binding protein that regulates transcriptional processes, meaning that its modulation will have profound effects on T cell differentiation and ultimate function by altering the expression of many genes.
