Where Medicine Meets Ecology

The human body is an ecosystem. Trillions of microbes call us home. They form the human microbiome, which performs critical functions that preserve our health including modulating our immune system and providing colonization resistance against infectious pathogens. Alterations of the human microbiome are increasingly recognized as a key factor in development of immune and infectious diseases.

We rationally design medicines based on consortia of human commensal bacteria to treat disease, using insights from microbial ecology, mucosal immunology, and human interventional studies.

A History of Breakthrough Science in Microbial Ecology and Immunology


Dutch scientist Antonie van Leeuwenhoek is the first person to observe bacteria, by scraping plaque from his own teeth and inspecting it through one of his handcrafted microscopes. His pioneering work contributed to establishing microbiology as a scientific discipline.

Carl Woese rewrites the Tree of Life with the discovery of Archaea. He pioneers the use of marker genes such as the 16S ribosomal gene as a method to distinguish between microbial lineages, greatly expanding our knowledge of the microbial world.


Vedanta cofounder Alexander Rudensky publishes key work describing the role of the FOXP3 gene in the process by which T cells become regulatory T cells, which can prevent autoimmunity.


David Relman publishes seminal work highlighting the great diversity of human-associated bacteria and urges consideration of a “second human genome project” aimed at cataloguing the thousands of microbes that live in association with humans.


The NIH launches the Human Microbiome Project to enable the comprehensive characterization of bacteria that live in association with humans.


Vedanta cofounders Dan Littman and Kenya Honda show that murine-associated bacteria (2009) and human-associated bacteria (2010) can induce intestinal Th17 cells, opening new avenues for the treatment of autoimmune disease via manipulation of the microbiome.


Vedanta Biosciences launched by PureTech Health and founders Ruslan Medzhitov, Alexander Rudensky, Dan Littman, Kenya Honda, and Brett Finlay, scientific pioneers in immunology and the human microbiome.


In landmark pharma partnership in the microbiome field, Vedanta enters into license agreement with Johnson & Johnson for a bacterial consortia drug candidate for inflammatory bowel disease, VE202.


Vedanta opens Cambridge state-of-the art facility for discovery and GMP manufacturing of bacterial consortia drugs.


Vedanta granted foundational patents in the microbiome field in the US and EU broadly covering drugs based on bacterial consortia containing Clostridium bacteria.
