The Lab Wardrobe

I played against type today, I am wearing a skirt, pretty shirt and cute shoes. To Lab. It's a good thing I have a lot of computer work planned!

Ah dressing like a scientist. The bleach-proof scruffy eternally dreary clothes. To be honest, there is something to be said for jeans, t-shirt and sneakers, after all that takes care of the general ick factor of exposed skin in the animal room or the slight overall scariness of working with radioactivity. But how long can one go on dressing "like a scientist"? Company t-shirts, jeans from six seasons ago. I'm tired of it, I have a whole wardrobe that doesn't get worn enough.

I think the true revolution is the ballet flat. They are great! Closed toes, flat, comfortable and go with everything. Practical and attractive, imagine that, whole new worlds have opened up. Bringing on the new wardrobe...

The Vocabulary

An Antigen is any molecule that is recognized by the specialized cells of the immune system, usually by antigen receptors on the surfaces of these cells. Antigens are picked up and displayed by other specialized cells called antigen presenting cells. Antigens can be recognized by two broad categories of cells, T cells and B cells. T cells detect antigens through an antigen receptor called the T cell receptor, but only when these antigens are bound to antigen presenting molecules called MHC molecules. MHC proteins carrying antigens are found on the surface of antigen presenting cells. B cells make antibodies, which also recognize antigens. Once a B cell recognizes antigens through its antigen receptor, the antibody, it makes many many more of the same antibody and secretes , or spits them out, into the body so that they circulate throught the body. Naive B or T cells are cells that have never seen an antigen, and activated cells are those that have. Effector cells are those cells that have seen antigen and can do something about it, like kill that the cell carrying the antigen. Memory cells are cells that retain a memory of their encounter with an antigen, and can react faster and more effectively the next time they see the same antigen. The immune system consists of a few major lymphoid organs: the thymus, where T cells are made; the bone marrow, where all cells originate; the spleen, where many effector cells reside; and the lymph nodes, which are present at multiple sites throughout the body. Immunes cells spend their lives whizzing around between these various organs in various states of activation. A pathogen is any organism that infects a host, they can be bacteria, viruses or parasites.
