34 year old male diagnosed with AIDS after testing HIV positive
Without T cells, the immune system lacks the adaptive immunity. Without these cells the body can't call on B Cells to secrete antibodies and macrophages. It's also difficult to get T cells to the infection to kill it
Immediate symptoms of HIV are fever, chills, headache, diarrhea, muscle aches and a sore throat.
AIDS stands for acquired immunodeficiency syndrome
Infections are much more common in people with HIV and AIDS. They lack the ability to fight off anything requiring the adaptive immune system
The only part of the immune system that doesn't work when HIV or AIDS is present is the T Cells
If left untreated AIDS will result in death via an infection- typically respiratory.
Monocytes - produced in the bone marrow, when they reach tissues they become macrophages or dendritic cells- these engulf foreign bodies through phagocytosis and eventually digest them
Eosinophils- helpful with allergic reactions, they monitor inflammatory response and trap substances / kill pathogens
Basophils - contain heparin, stops blood from clotting too quickly & histamine to keep blood flow in tissues
B cells - They help with humoral immunity in the adaptive immune system by multiplying and secreting the antibodies found by the T cells through out the body
Natural killer cells - They work to control the spread of ifnection by killing the cells infected as well as your own body cells. They keep killing cells until a solution is found by the T and B cells in the immune system.
T cells - originate in bone marrow and mature in the thymus, these cells keep track of what antibodies you have in your adaptive immune system
Neutrophils - first responders to sight of infection
Innate immune system
Nonspecific defense mechanism
Skin, hair, and mucus membranes work to keep pathogens OUT
Immune systems first and second response
Triggered by antigens (anything that doesn't have YOUR specific "code" saying its supposed to be there
Chemicals in the blood and white blood cells work to attack pathogens or anything that isn't supposed to be there (macrophages and NK cells)
Macrophages "eat" pathogens and digest them via phagocytosis. NK cells work to kill pathogenic cells as well as anything else in the way - including your own cells, part of the reason we have symptoms!
Adaptive immune system
B cells then work to duplicate the necessary antigen to fight against the infection
Has a memory, why we use vaccines- you get a small dose for T cells to work , so if acquired again the body has the antigen stored to fight off that specific pathogen
T cells work to identify the antigen
HIV is a virus that is spread via body fluids (blood, semen, renal fluid, vaginal fluid and breast milk) while AIDS is the disease acquired when the immune system is damaged beyond repair.
HIV can be spread through sex or by using a dirty needle. It can also be passed between mother and child when breast feeding, sharing devices used during sex, and an accidental dirty needle stick
HIV becomes AIDS when the body has less than 200 T cells per cubic mm. AIDS is hen HIV has damaged the body beyond compare
HIV and AIDS stop T cells from functioning- this means your immune systems memory can't function and find the correct antigen to fight off any pathogens and you just get more and more sick as time progresses.
HIV is a virus that stops helped T cells from working in the immune system. AIDS is the continuation of that virus as it progresses into a disease that stops the immune system from working
In the lysogenic cycle of a virus leads to the integration of viral DNA into the host's DNA
In lytic cycle of a viruses, viral DNA is in a free floating molecule within the cell
types of infection and how they're treated
antibiotics are used to fight bacterial infections by disrupting the necessary cell growth and stop the infection.
you can't fight a viral infection, you can only take medicines to help ease the symptoms while your body's immune system works to fight off the virus. Vaccines are used to fight many viruses
organs and cells of the immune system
White blood cells
Monocytes / become macrophages
