Now, in a surprising new discovery, Harvard Medical School researchers have found that a class of regulatory T cells (Tregs) made in the gut play a role in repairing injured muscles and mending damaged livers. In an even more unexpected twist, the researchers found that gut microbes fuel the production of Tregs, which act as immune healers that go on patrol around the body and respond to distress signals from distant sites of injury.

Uma colonização específica de micróbios no trato reprodutivo é comumente encontrada em mulheres com câncer de ovário de acordo com um novo estudo do Centro de Medicina Individualizada da Mayo Clinic. A descoberta, publicada na revista Scientific Reports, fortalece a evidência de que o componente bacteriano do microbioma (uma comunidade de microrganismos que também consistem em vírus, leveduras e fungos) é um importante indicador para detecção precoce, diagnóstico e prognóstico do câncer de ovário.

Según un nuevo estudio del Centro de Medicina Personalizada en Mayo Clinic, se suele hallar una colonización específica de microbios en el aparato reproductor de las mujeres con cáncer de ovario. Este descubrimiento, publicado en la revista Scientific Reports, refuerza las pruebas de que el componente bacteriano del microbioma (una comunidad de microorganismos que incluye virus, hongos y levaduras) es un indicador importante para la detección temprana, el diagnóstico y el pronóstico del cáncer de ovario.

In APL Bioengineering, researchers describe how gut-on-a-chip devices can bridge lab models and human biology. Modeling the microbiome is particularly difficult because of its unique environmental conditions, but through creative design, gut-on-a-chip devices can simulate many of these properties, such as the gut’s anaerobic atmosphere, fluid flow, and pulses of contraction/relaxation. Growing intestinal cells in this environment means that they more closely resemble human biology compared to standard laboratory cell cultures.
