When infected by a cold virus, some people can get sick and others don’t, writes ScienceDaily. Scientists from Yale University were able to establish that the cells of the respiratory tract respond differently to cold.
Cells of the respiratory tract protects against viruses and other harmful substances that penetrate inhalation of air. This air passes through the air path, the inside is lined with epithelial cells recognizing undesirable particles. The researchers found: when faced with one stimulus at a time, purifying the air path are functioning actively, but if there is a lot of stimuli, epithelial cells “distracted” and can miss a virus.
In particular, the researchers found that when the virus to penetrate the respiratory tract cigarette smoke or tree pollen, nasal antiviral protection of the cells might not work. This is due to the fact that the cells are involved in the fight against cigarette smoke. Thus smokers can be considered more prone to infection rhinovirus infection.
Overall, the authors of the study, their work confirms the existence of mechanical linkage between environmental exposures and susceptibility to the common cold.
