College of California San Diego and College of California Berkeley researchers have been awarded as much as $7 million from the Superior Analysis Tasks Company for Well being (ARPA-H) to conduct analysis beneath the PROTECT mission -; Professional/Prebiotic Regulation for Optimized Remedy and Eradication of Scientific Threats. The mission targets pathogens akin to Pseudomonas aeruginosa and probably Staphylococcus aureus, which pose vital well being dangers for people with cystic fibrosis and people depending on respirators. PROTECT co-principal investigators are Karsten Zengler, Ph.D., professor within the Departments of Pediatrics and Bioengineering at UC San Diego and Adam P. Arkin, Ph.D., Dean A. Richard Newton Memorial Professor at UC Berkeley’s Division of Bioengineering.
We’re excited to start this vital endeavor and grateful to ARPA-H for his or her imaginative and prescient. This analysis might pave the best way for a brand new modality to optimize dosing and monitor lung well being, significantly for people affected by cystic fibrosis, a uncommon but debilitating genetic situation with no recognized remedy. This mission represents an revolutionary technique to sort out infectious ailments in methods beforehand unexplored. If profitable, this expertise will revolutionize how we strategy microbe-related diseases.”

The PROTECT mission seeks to fight lung infections by assembling a neighborhood of useful lung microbes that may outcompete dangerous pathogens. Researchers will establish probiotic micro organism from wholesome people’ microbiomes, specializing in these able to thriving alongside the host whereas metabolizing substances that invading pathogens require to outlive and proliferate. By enhancing these aggressive interactions, the mission goals to guard lung well being and observe the effectiveness of those probiotics via engineered signaling molecules. Initially, the mission will concentrate on cystic fibrosis and bronchiectasis, with the potential for broader purposes.
The work might be achieved in phases over 4 years. The primary section facilities on figuring out and analyzing aggressive niches throughout the airway microbiome, significantly specializing in Pseudomonas aeruginosa. The researchers will recruit and pattern from affected person cohorts to establish bacterial strains and their metabolic profiles, emphasizing these related to cystic fibrosis and bronchiectasis. It’s going to then carry out meta-functional genomics to grasp microbial interactions and metabolic traits crucial for designing efficient probiotic formulations. The formulations of pre- and probiotic interventions might be examined in cystic fibrosis mouse fashions to acquire compositions which might be readily translatable to the clinic.
Pseudomonas aeruginosa, a Gram-negative bacterium, is among the most vital and incessantly antibiotic-resistant pathogens in cystic fibrosis affected person populations. Present in 60 to 80% of adults with cystic fibrosis, it’s related to speedy lung operate decline and elevated pulmonary exacerbations – a big and sudden worsening of signs in folks with cystic fibrosis. Continual infections result in larger mortality charges and a considerable healthcare burden as a result of frequent hospitalizations and antibiotic therapies. Eradicating Pseudomonas aeruginosa provides vital scientific advantages, underscoring the pressing want for brand spanking new therapies. It’s also a number one reason for hospital- and ventilator-associated pneumonias, representing one other crucial unmet medical problem.
UC San Diego’s multidisciplinary staff for this mission consists of Fatemeh Askarian, assistant mission scientist of pediatrics; Douglas Conrad, professor of medication and director of the Grownup Cystic Fibrosis Clinic; Chantal Darquenne, adjunct professor of medication; Patricia Lenhart-Pendergrass, assistant adjunct professor of pediatrics; and Victor Nizet, distinguished professor and vice chair for fundamental analysis within the Division of Pediatrics.
The mission has a funds of as much as $22.7 million.
