Γδ-T cells have been found to have trophic properties for intestinal and cutaneous epithelial cells . There is also evidence that they could have a part in the airways, though they are significantly less several there than in the aforementioned tissues. It seems that chlorine causes much more airway injury in γδ-T cell–deficient mice . Following chlorine exposure, the numbers of epithelial cells in the BALF of mice that are deficient in γδ-T cell receptor is higher than in wild-variety animals . The inflammatory response to chlorine exposure is delayed in the γδ−/− mice, and the adjust in airway responsiveness to methacholine is also diminished. This suggests that the inflammatory response to chlorine exposure may well contribute to the raise in responsiveness in addition to the much more direct effects mediated by epithelial cell harm.

Following this attack, the Germans led repeated chlorine gas attacks near Ypres but failed to capture the town. The current public debate about chlorination issues the direct health impact from ingesting chlorine and the by-merchandise that may possibly be formed in chlorinated drinking water. There are reports that indicate that no cost chlorine causes fats to form cholesterol deposits that may perhaps clog arteries. Cellular injury is believed to outcome from the oxidation of functional groups in cell components, from reactions with tissue water to form hypochlorous and hydrochloric acid, and from the generation of totally free oxygen radicals. Although chlorine was at a single time thought to bring about direct tissue damage by generating free oxygen radicals, this concept is now thought of controversial. Chlorine gas, when mixed with ammonia, reacts to form chloramine gas.
