me: what are taxes and how do I pay them?

school system: worry not

school system: mitochondria is the powerhouse of the cell

Seriously though, why doesn't school tell me how to file tax returns, or put gas in my car, or apply for a credit card.

The human leukocyte antigen (HLA) system is the locus of genes that encode for proteins on the surface of cells that are responsible for regulation of the immune system in humans. This group of genes resides on chromosome 6, and encodes cell-surface antigen-presenting proteins and has many other functions.

The HLA genes are the human versions of the major histocompatibility complex (MHC) genes that are found in most vertebrates (and thus are the most studied of the MHC genes). The proteins encoded by certain genes are also known as antigens, as a result of their historic discovery as factors in organ transplants. The major HLAs are essential elements for immune function. Different classes have different functions:

HLAs corresponding to MHC class I (A, B, and C) present peptides from inside the cell. For example, if the cell is infected by a virus, the HLA system brings fragments of the virus to the surface of the cell so that the cell can be destroyed by the immune system. These peptides are produced from digested proteins that are broken down in the proteasomes. In general, these particular peptides are small polymers, about 9 amino acids in length.[citation needed] Foreign antigens presented by MHC class I attract killer T-cells (also called CD8 positive- or cytotoxic T-cells) that destroy cells.

HLAs corresponding to MHC class II (DP, DM, DOA, DOB, DQ, and DR) present antigens from outside of the cell to T-lymphocytes. These particular antigens stimulate the multiplication of T-helper cells, which in turn stimulate antibody-producing B-cells to produce antibodies to that specific antigen. Self-antigens are suppressed by regulatory T cells.

HLAs corresponding to MHC class III encode components of the complement system.

HLAs have other roles. They are important in disease defense. They are the major cause of organ transplant rejections. They may protect against or fail to protect (if down-regulated by an infection) against cancers. Mutations in HLA may be linked to autoimmune disease (examples: type I diabetes, coeliac disease). HLA may also be related to people’s perception of the odor of other people, and may be involved in mate selection, as at least one study found a lower-than-expected rate of HLA similarity between spouses in an isolated community.

Aside from the genes encoding the 6 major antigen-presenting proteins, there are a large number of other genes, many involved in immune function, located on the HLA complex. Diversity of HLAs in the human population is one aspect of disease defense, and, as a result, the chance of two unrelated individuals with identical HLA molecules on all loci is very low. HLA genes have historically been identified as a result of the ability to successfully transplant organs between HLA-similar individuals.

Sometimes I just want to report something as "pleomorphic, Gram variable coccobacilli"

Oh micro, I was kind of good at you once upon a time. But now I miss you and get confused.

Hey guise, I still don't have ebola.

It's pretty close to me though, proximity wise (and I know people who work in the lab at Presby Dallas and have had contact with Ebola ladden specimens)

But yep. Still Ebola free so far. Pretty good day. Although I did get some bleach on my scrubs last night.

So I don't work at Presby, but I do work at another hospital in the DFW area. So this is definitely pretty close to home. Best wishes for the patient, the healthcare workers, and any others who could have been exposed. 

I'm sure many of you have seen this in your work e-mail, but for those who haven't, here's the CDC's recommendations for dealing with ebola samples/patients:

PS- if I have any followers that work at Presby, I'd love to hear from you. You can stay anon, obviously, but I'd love an inside scoop :)

Literally me when a nurse calls to complain that a phlebotomist isn't there yet. By the time we have this whole conversation of you complaining, you could have drawn the blood yourself. 

Also, we have absolutely no control over phlebotomists. I can't control anything they do or don't do.

Not med lab related, but the destruction of ecosystems is important, yo.
