Last year, our sister biotech company @LUCABiologics announced VIRGO, the first comprehensive reference in the gene catalog of the human vaginal #microbiome spearheaded by Chief Scientist Dr. Jacques Ravel. A thread 🧵
This database of nearly 1 million non-redundant genes reveals significant genomic and functional diversity within the vaginal #ecosystem, challenging the widely-held notion that an optimal vaginal microbiome is dominated by one strain. 🧵
This new view of intraspecies diversity has deep implications on the development of gene-centric, microbial therapies to target #diseases like bacterial vaginosis, urinary tract infection, and STI, which impact millions of women globally.🧵
Right now, the only frontline treatment is antibiotics, despite extensive side effects, failure to prevent recurrence, and the alarming rise in #antibiotic resistance. The need for innovation has never been more urgent.🧵
LUCA is looking to #microbes to develop a new category of ‘living medicines’ that modulate the vaginal microbiome to impact health. The first focus will target #UTIs with our future pipeline addressing BV, #infertility, and preterm birth. 🧵
Sound on 🔈— In this video, the sound of a healthy yeast cell has been made visible on the CymaScope instrument, revealing complex geometrical features. The study of the sound of cells is known as #sonocytology—read more below. (Video credit: CymaScope on YouTube) 1/4
Sonocytology (first discovered by Dr. James Gimzewski) uses an atomic force microscope (AFM) to scan over the cell’s surface creating a precise map of its topography. The AFM records the vibrational movements of cell walls, amplifying these vibrations into audible #sound. 2/4
Saccharomyces cerevisiae oscillate at approximately 1,000x/second (reminiscent of amplitude + frequency of sound waves). Interestingly, when exposed to alcohol, the pitch of these vibrations increases—something Gimzewski referred to as ‘screaming’. doi.org/10.1086/596646 3/4
