Check with the classroom teacher and the school first about foods that should not be brought into the school building. Some children have extreme allergies, such as to peanuts, and can react to minimum contact like touching a door handle that had been previously touched by someone handling something with nuts. Any food can cause an allergic reaction, but milk, soy, eggs, wheat, peanuts, tree nuts, fish and shellfish allergies are some of the most common.Kv channel blockers and channelspecific shortinterfering RNAs (siRNAs) were used to assess their roles in RGC degeneration. We found that (i) rat RGCs express Kv1.1, Kv1.2 and Kv1.3 (but not Kv1.5); (ii) intraocular injection of agitoxin2 or margatoxin, potent blockers of Kv1.1, Kv1.2 and Kv1.3 channels, dosedependently reduced the RGC degeneration; (iii) siRNAs applied to the cut optic nerve were rapidly transported throughout RGCs only, in which they reduced the expression of the cognate channel only. Our results show differential
