NSF funds UCSB-led Biofoundry to revolutionize biotechnology with unexplored microbes

This week, the National Science Foundation announced the award of a six-year, $22M grant to UC Santa Barbara under its biofoundries program for the establishment of the BioFoundry for Extreme and Exceptional Fungi, Archaea and Bacteria (ExFAB), a collaboration led by UC Santa Barbara (UCSB), together with UC Riverside (UCR), and Cal Poly Pomona (CPP). ExFAB establishes the nation's first biofoundry that focuses on largely untapped and unexplored extreme microbes. UCSB's award is one of only five grants made under NSF's BioFoundry program during this funding cycle, which awarded a total of $75M to the five selected universities.

New insights into AD pathogenesis and treatment

The main text of the study details the experiments conducted to understand the role of IL-24 in AD-like conditions. It describes the methods used, including single-cell RNA sequencing, and the animal models employed to mimic AD. The findings indicate that MRSA infection leads to increased IL-24 in keratinocytes, which in turn heightens type 2 immune responses and worsens AD symptoms.

Benefits of less intensive stem cell transplants for sickle cell disease

So-called low-intensity blood stem cell transplants, which use milder conditioning agents than standard stem cell transplants, do not appear to damage the lungs and may help improve lung function in some patients with sickle cell disease (SCD), according to a three-year study of adults who underwent the procedure at the National Institutes of Health (NIH).

LncRNA ZNF593-AS offers hope for heart disease treatment

The research presented in the article delves into the regulatory role of the long non-coding RNA (lncRNA) ZNF593-AS in cardiac hypertrophy and myocardial remodeling, processes that are pivotal in the progression of heart failure and other cardiovascular diseases. The study uncovers how ZNF593-AS exerts its inhibitory effects by upregulating the expression of Mitofusin 2 (Mfn2), a protein known for its role in the regulation of mitochondrial dynamics and cellular metabolism.
