The Helper T Cells: A Short Story

The scientists discover that the disease kills through coagulation or clotting of the blood, but it could also cause insanity due to the blood in the brain clotting. The newborn and the old man survived because their blood was more acidic than the rest of the town. When one of the scientists on the team is exposed to the disease they realize that at that point the disease had mutated and became harmless.

Ms. Hines' kids played in the water, Mrs. Garner's didn't. 3. Mrs. Ganer's class visited the petting zoo, could they also have become sick from microorganisms?

Mary Mallon was a victim when she was quarantined for the first time. Science had not been developed enough yet to prove and explain what healthy carriers

The third and final wave of this lethal killer came in the spring of 1919. Although this mutation was less deadly than its predecessor, it still devastated communities as it continued to add to the death toll. This outbreak was responsible for taking away ten years from the average life expectancy of a person, kept people in a constant panic, and “In its wake, the pandemic would leave about twenty million dead across the world. In America alone, about 675,000 people in a population of 105 million would die from the disease.3” Governments and private organizations both scrambled to find a cure and in 1918 they believed they might have found the source of the virus to be a bacteria rather than a virus. They operated under that assumption until

1.1.6 Final Report An outbreak occurred on the campus of Ottawa University. An investigation was necessary to find the cause of the outbreak, and how to stop it from continuing to spread. The campus clinic was interested in testing the following nine patients: Sue, Jill, Anthony, Wanda, Maggie, Maria, Arnie, Marco, and Alvin. All of the students have similar symptoms and agreed to being tested except for Alvin.

     The government,      When the satellite crashes to Earth, the special team of four people that the government had previously selected, was called to this building. They had samples of the organism, which was found by other people at the crash site sent to the building. They were going to use this sample to research the organism. They hoped to find out what it was and how it killed all of the people who lived in the small town in Arizona. Everything was going well with the research, until the virus started eating through plastic containers and the sterile suits that the workers were wearing. After time, almost all of the workers who were in the building had been killed by this virus. The only person that lived out of the five people who were on the selected team was Mark Hall.

A baby bottle gets shoved away, a plate of noodles get's a no-no reply, and a pacifier is rejected, but one certain item put a huge smile on this baby's face. 14 month-old Abigail Aybar was not happy with any of the tricks her parents had up their sleeves when they were trying to make their cranky daughter happy, until they flashed an item in front of her she couldn't resist.

Eyes- A sight that affected her was when she saw her left arm gone and saw the bright red water besides her. She remembers this moment because is was when the shark had attacked her and she had the thought that she wouldn’t be able to surf again.” I remember seeing the water around me turn bright red

Annoyed, I slammed my laptop closed. The proclaimed "Apocalypse" had started nearly two weeks ago, at a lab in North Dakota. Originally, the parasite was a mosquito that was engineered to breed with other mosquitos to modify

Spiky, miniscule organisms attack. They travel through fluids aimed at the arm and hope for death at contact. Instead they enter an entirely new world full of red disks that sink at the bottom (red blood cells), purple worms in white casings (white blood cells) and white, clay-like splatters (platelets). They slowly travel through, as if the world has sat upon them. These are weakened pathogens. Suddenly, as they slide like snails, circular figures attach to them with great force. They stare with beady, invisible eyes. All of the sudden, they vibrate. Y-shaped cells come out of the shadows and attach to the unusual circular figures. The spiky pathogens approach the Y figures to thank them, just to be approached by the Y figures. They are overwhelmed by a sudden attack and pull back, or at least try to.

However, the most memorable thing I was able to see that day was the human brain. Looking at it, it didn’t look much different than models we had used in class. The student in charge of that section went over the fundamental parts of the brain, things I had studied for class. Though it was interesting, the moment that made it really real for me was the moment I was able to hold it. Holding it is my hand, the basic anatomy of the brain went away. I stood in an awed silence as I tried to imagine the things it had seen, had heard, the life it had lived. This was the motor to human existence. Though brains may look similar on the outside, on the inside they were so unique, so different, each like a snowflake, only ever occurring once. It was in that moment that I knew I wanted to learn all I could about this fascinating object that is the mind, unlock doors that had previously been closed, and leave the world a better place than I found it.

As she walked towards the kitchen she stopped in her tracks, then slowly turned around. Yet, she saw nothing out of place when her eyes swept the room. What have I missed? she asked herself.

Positive selection: Positive selection permits the survival of only those T cells whose T cell receptors (TCRs) are capable of a self MHC restricted repertoire of T cells. Cells that fail positive selection are eliminated within the thymus by apoptosis. Negative selection: Negative selection eliminates T cells that react too strongly with self MHC or with self MHC and self-peptides bearing high affinity receptors for self MHC molecules alone or self-antigen presented by self-MHC, which results in self-tolerance. It is an extremely important factor in generating a primary T-cell repertoire that is
