Document Summary

Lesson 2. 5 hiv the basics [reading review] Immunodeficiency means a weakened immune system (which is what defends your body against disease) Hiv attacks the body from the inside and also leaves the immune system weak enough that it is very likely to become sick from other things as well. When hiv is not treated properly a patient may become sick with a life-threatening infection (aids) With proper treatment, many people now with hiv avoid getting aids and live healthy lives. The simplest and smallest of all living things. Viruses don"t reproduce on their own, but infect living cells and trick them into creating more infected cells. Hiv is so dangerous because it infects cd4+ cells, cells meant to fight of infection. Infection happens when enough hiv from an hiv+ person gets into an hiv- s body. Only happens when body fluids with high amount of virus get into the other person"s body.

Antibodies are also called immunoglobulins and constitute part of the blood proteins. How do antibodies work?

Agglutination-- they just clump with each other (blocking antigen)

Precipitation-- force insolubility and settled out of solution along with antigens

Complement fixation-- proteins attach to antigen surface (causing cell lysis)

Neutralization-- bind to specific sites to prevent antigen attachment

All of the above

Homework

HIV has which of the following characteristics?

It has an enzyme called reverse transcriptase which causes the DNA to reverse the nucleotide sequence in messenger RNA.

It is a retrovirus meaning that it reverses the order of protein production in that the virus affects the DNA in the cell to make the protein.

It is an anti-retrovirus meaning that it attacks the DNA causing the development of new HIV particles.

It has a short incubation period which means that the symptoms show up also immediately after infection.
