Infection TRIM21 marks viruses and bacteria for degradation via autophagy TRIM21, an enzyme involved in intracellular substrate degradation, can recognize viruses and bacteria that enter the cytosol when they are coated with antibodies. Just as it tags complex molecules for elimination, it can direct these infectious microorganisms to lysosomes through a mechanism its discoverers have termed antibody-directed xenophagy (ADX).

Respiratory Innate immunity and microbiome allied against pulmonary fibrosis The microbiome and a frontline innate antimicrobial sensor, Toll-like receptor 5 (TLR5), play an essential role in the development of idiopathic pulmonary fibrosis (IPF). A scientific collaboration led by researchers at the National Institute of Environmental Health Sciences has revealed how TLR5 protects against fibrosis through its ability to modulate the lung microbiome.

Cancer Pancreatic lesions show cancer traits but lack stromal support The human pancreas often contains lesions that are common in the population and that, although they can become malignant, usually do not. To understand when this occurs and how these pancreatic cancer precursor lesions, known as pancreatic intraepithelial neoplasias (PanIN), evolve, scientists at the University of Michigan analyzed their gene expression patterns and their cellular microenvironment.
