How the smallest bacterial pathogens outwit host immune defenses by stealth mechanisms

Despite their relatively small genome, mycoplasmas can cause persistent and difficult-to-treat infections in humans and animals. A study has shown how mycoplasmas escape the immune response. Mycoplasmas ‘mask’ themselves: They use their small genome in a clever way and compensate for the loss of an enzyme that is important for this process. This could be […]

Chromosomes may be knotted

Little is known about the structures of our genetic material, chromosomes, which consist of long strings that — according to our experience — should be likely to become knotted. However, up to now it has not been possible to study this experimentally. Researchers have now found that chromosomes may indeed be knotted. Source: Feed4
