Bugs in the gut could play key role in understanding human disease and drug toxicity
...ntain more genes than the host. The combination of interacting genes from the body and gut microbes can be considered a 'super-organism', capable of co-ordinating many physiological and metabolic responses, say the researchers. Professor Jeremy Nicholson, from Imperial College London, and lead researcher comment...HHMI researchers Richard Axel and Linda Buck win 2004 Nobel Prize
...like shape. They also function in similar ways, by interacting with G proteins to transmit signals to the cell's interior. Since many receptors of this type share certain DNA sequences, Buck designed probes that would recognize these sequences in a pool of rat DNA. Next, she assumed that the odorant receptors ar......m Africa replaced archaic humans elsewhere without interacting with them, the type of lice on archaic humans would have gone extinct with their hosts instead of jumping to modern humans.
