http://en.wikipedia.org/wiki/Narcolepsy

I added a citation where one was needed. The article was difficult to edit because it was basically a copy from an external .org cite that covered the disease extremely thoroughly. 

http://en.wikipedia.org/wiki/Rheumatoid_arthritis#Genetics

I added some information to the genetics section about genes that have been linked to RA inheritance with an additional citation.

World in Conversation

I attended World in Conversation last Tuesday and it ended up being one of the more enriching experiences I've had at Penn State thus far. Half of my group was other students from our seminar, and the other half were students from the regular VBSC seminar; the composition made it really nice because everyone there knew at least one other person which allowed the conversation to flow more smoothly. We talked about racism in America and how equality is/ has been progressing. 

Overall the experience was extremely enlightening and definitely something that should continue to be required for freshman in the future. 

So about those bats..

From the point of view of a zoonosis, bats are an ideal medium for disease transmission. They live in large colonies, accelerating the spread of disease through their own population, and often come into contact with other species, including our own, in both direct and indirect ways. Humans have begun to infringe upon bat territory by cutting down the rainforests that house many bat species, thereby closing the demographic gap between the two. But buts can also affect other species by contaminating their food sources with diseased fecal matter, because they can fly, they can easily rain disease down upon the fruits, vegetables, and other organic matter many organisms ingest regularly.

Main Ideas
One. Our immune system has two different types of response to pathogens, one being innate (non-specific), and the other being adaptive (specific). Innate immune response is with us at birth, and is the simpler of the two. It's the body's first line of defense and works by attacking the pathogen in a non-specific way. Oppositely, there is adaptive immunity which works when a pathogen the body has already seen makes a reappearance. The body is now "adapted" to the pathogen and can target it specifically, removing it with the help of memory cells. 

Two. There are two different types of immunity, one being humoral and the other being cell-mediated. In humoral immunity, B-cells secrete antibodies to eradicate pathogens in the blood. In cell mediated immunity, T-cells kill cells already infected by the pathogen. 

Three. The body's cells are labeled with self-tags, which prevent autoimmune diseases from occurring. T cells are able to identify the cells as self-cells, and therefore don't mount an immune response against them. 

What?
The most confusing thing about the lecture were the names of the cells, B and T sound so similar is was easy to get them confused. I understand that we only have an hour but the information came so fast it was hard to get a grasp on which cell was doing what, where. 

First Lecture!

Today was a nice review of a lot of things that were covered in my high school biology class, but that I haven't talked about for a while. I also learned more about microRNA, which is a type of RNA that regulates gene expression after transcription has already taken place. 

One thing that confuses me, is double stranded RNA. I know we only touched on it briefly, but I would've like to learn more about how it works with viruses and with RNAi.

For real this time, this is my first post.
