I’m a Scientist is like school science lessons meet the X Factor! School students choose which scientist gets a prize of $1000 to communicate their work.
Scientists and students talk on this website. They both break down barriers, have fun and learn. But only the students get to vote.
This zone is the Organs Zone. It has scientists studying health and disease in various parts  of our bodies. Who gets the prize? YOU decide!
Hi jelly,
Good question.
There are normally only 2 types (not really, but let’s not get carried away with the complexities!). What I mean is that in your eye, when its naturally healthy with no scratches or anything, there are dendritic cells and macrophages.
Dentritic cells have these processes, or arms, which make it look like an octopus. The main role of these cells is to “sample” the area around them, searching for anything out of place!
Macrophages are phagocytic in nature, meaning the gobble things up and digest them.
These 2 cell types keep the eye in tip-top shape by cleaning up anything that they “sense”.
The complexity I mentioned earlier is that there are different classes of DCs and macrphages; and that these cells talk with other white blood cells circulating in your blood when your cornea gets inflammed to start an immune response. This involves many more cells, and we’ll be here for a long time! LOL
Summary, normal cornea has dendritic cells and macrophages throughout its layers 😀
