Question: What type of white blood cells are at work in our corneas'?

Keywords: ,

  1. 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 😀
