"Human T-cells--the system Nolan and Lauffenburger's team used to validate their technique--rely on a complex signaling network to protect the body from pathogens such as viruses. When a T-cell encounters a foreign invader, it relays a danger signal throughout the cell, activating it for a quick response."

This is import because we need to know how Human T cells work and we should be able to understand them because they are apart of us and we need to know how we function.

ReplyDeleteIn the article from the NSF it shows how cells work together. The cells need each other to function properly. The cells send signals to each other. In the paragraph it shows how cells need one another."Such alterations occur only at points of active signaling in the network. The researchers measured the modified signaling molecules to determine where along the pathway T-cell components changed in response to signals. An increase in the amount of the molecules indicated spots where they were most active."

"Tracing the individual pathways that guide information flow inside cells is a difficult task using standard experimental methods. Multidisciplinary research teams are working on new approaches to make the process faster and easier."

I thought this was very important because it showed that the scientists have to think outside the box to make research faster and easier.

DeleteI think map cellular signaling network would be significant for scientists to help cells communicate with each other because this way they can direct if something goes wrong with the cell. They can see if something went wrong with the function of the cell or if something entered the cell that wasn't suppose to. If scientists know the the network of the cell they can fix anything that goes wrong with it.
ReplyDelete"Scientists have treated signal networks like a puzzle--studying them one pathway at a time and then tying the information together to construct a global picture of what’s going on inside the cell."

I think this is significant because there are many factual things about the living cell. They live in our everyday life and they help us achieve things everyday.
ReplyDelete"To function properly, cells must be able to detect changes in the environment and respond accordingly--usually by altering their behavior in some way. Cells are equipped with a sophisticated communications network that links surveillance with response, and allows the cells to perform a variety of tasks--such as growing in response to hormones, moving towards a source of nutrients, or responding to foreign invaders in the body. In all of these cases, external signals are converted into cellular messages that get passed sequentially from one molecule to another. Tracing the individual pathways that guide information flow inside cells is a difficult task using standard experimental methods. Multidisciplinary research teams are working on new approaches to make the process faster and easier."

I think it would be significant for scientists to be able to map cellular signaling network that help cells communicate with each other because Scientists won't have to deal with it as a puzzle. "In the past, scientists have treated signal networks like a puzzle--studying them one pathway at a time and then tying the information together to construct a global picture of what’s going on inside the cell." The cell communication will make it work in a more improved way. It will decrease the number of cell malfunctions.

I think that this was interesting because it talks about how cells communicate and how their communication allows them to perform different tasks.

ReplyDeleteThis quote is important because cells alter their functions to send signals to each other such as producing more hormones. It would be important for scientist to be able to map cell signaling because it will help them understand how the cell works and its complexity.

This is interesting to me because cells communicate no where near the way humans do. They alter their functions to send signals to each other and produce more hormones. " Cells are equipped with a sophisticated communications network that links surveillance with response, and allows the cells to perform a variety of tasks--such as growing in response to hormones, moving towards a source of nutrients, or responding to foreign invaders in the body.

I think this is important because it tells the reader that cells are equipped with sophisticated communications that they need in order to function.

"Human T-cells--the system Nolan and Lauffenburger's team used to validate their technique--rely on a complex signaling network to protect the body from pathogens such as viruses. When a T-cell encounters a foreign invader, it relays a danger signal throughout the cell, activating it for a quick response. These signals prompt activated T-cells to multiply rapidly and send out molecular "distress signals" that attract other immune system molecules to battle the infection. Components in the pathway are chemically altered during the signaling."

I think it would be significant for scientists to be able to understand how cells communicate because they might be able to catch cases of cancer earlier and be able to understand how cells are programmed to reproduce so we could regrow limbs if we learned how to override that communication. We could learn how diseases spread and how our cells combat them. We could also possibly learn how to fix problems in genetic code inside the cells. In conclusion, to understand how cells communicate with each other would benefit the world a whole lot.

"In the past, scientists have treated signal networks like a puzzle--studying them one pathway at a time and then tying the information together to construct a global picture of what’s going on inside the cell. But the molecules that make up individual pathways in signaling networks rarely operate in isolation--they "talk" to each other and work in sync to process information. What researchers have lacked are the experimental and computing tools to model entire signaling networks at once. This new work should help bridge that gap."

I think that this article is interesting and important because it explains what cells need in order to function properly. We should know and understand how cells communicate with one another because it's important that we know about what goes on in our cells so that we are able to work with them and understand everything about them.

ReplyDeleteit is important to know how cells can communicate because of many things, like when doing life threatening surgery and something was wrong then the doctors could make some changes and make it a more safe surgery in which people won;t be as scared as before. Also with this we can find a way in which cells can work together to find cures of crazy diseases like cancer or ebola.
In order to function properly, cells have to be able to detect changes in their environment and adapt to their surroundings. Cells have a sophisticated communications network that links surveillance with response. This allows them to do a multitude of things such as moving towards a source of nutrients, growing in response to hormones, and acting against foreign substances.
ReplyDeleteI think this is important and interesting because it talks about what cells need to do in order to survive. It also explains how certain parts of the cell functions. The more we learn about cells, the more we can understand them, study them, and apply the knowledge in other areas.
