Effective immunity hinges on the ability to sense infection and cellular transformation. In humans, there is a specialized molecule on the surface of cells termed MR1. MR1 allows sensing of certain small molecule metabolites derived from cellular and microbial sources; however, the breadth of metabolite sensing is unclear. Researchers have identified a form of vitamin B6 bound to MR1 as a means of engaging tumor-reactive immune cells.

Researchers have developed a patch for easier and more effective treatment of psoriasis. The method may also be used in treatment of other inflammatory skin diseases.

Mechanical engineers have developed a system of artificial cilia capable of monitoring mucus conditions in human airways to better detect infection, airway obstruction, or the severity of diseases like Cystic Fibrosis (CF), Chronic Obstructive Pulmonary Diseases (COPD) and lung cancer.

Windblown dust from the shrinking Salton Sea harms the respiratory health of children living nearby, triggering asthma, coughing, wheezing and disrupted sleep, USC research shows. The problem is likely to intensify in a hotter climate, with evaporation exposing more and more of the lake bed, or playa, leading to more dust events.

As critical responders, macrophages can perceive helpful biotechnology as threats. If not created with the right materials or mechanical forces, these devices can trigger an immune response that can cause inflammation, scar tissue or device failure.
