What do vaccines do compared to antihistamines
Vaccines can boost protective features of the immune system to prevent infections. Antihistamines can block harmful effects of incorrect immune cell functions that cause symptoms of allergies.
5 signs of inflammation
heat, redness, pain, swelling, loss of function
Innate immunty
Non-specfic
occuring immediately after a threat is encountered in the body
Adaptive immunity
Specific cellular
Complex and specific response learned to create an immune “memory” for future protection
What is a macrophage
Macrophages are all over the body and patrol and keep order. These innate immune cells internalise and kill pathogens and remove dead cells in healthy and infected tissue. They process antigens of the threats they eat, using that to teach other cells. They also help to repair wounds
What is a natural killer cell
They are specalists. These innate immune cells are licensed to kill. Carrying dangerous weapons in granules, they kill infected cells and tumour cells
What is a neutrophil
Neutophils are the military force called in when things might get out of control. These innate immune cells respond quickly, internalise and kill pathogens, signal to other cells, and release killer NET traps
What is eosinophils
Eosinophils have special weaponry, making these innate cells effective at pathogen killing. However, this weaponary needs careful control to avoid allergic reactions
What is a mast cell
Mast cells are innate immune cells with specalised chemical weapons kept inside granules. They release these to signal danger to other immune cells, kill pathogens, and increase blood flow to the site of infection
What are denritic cells
Dendritic cells are the bodys surveillance team. Spying, sampling, and testing everything. They internalise and process antigen, which they use with other signals to teach adaptive immune cells what to do.
T helper cells
T helper cells are trained specalists, a support part of the adaptive immune system. Activated by a perfectly matching antigen, they divide to create a clone army. This army signals to other cells to set up the ideal fighting force response. They then form a long lasting immune memory to protect the body from future attack
What is a cytotoxic T cell
Cytotoxic T cells are trained specialists; killer cells of the adaptive immune system. Activated by a perfectly matching antigen, they divide to create a clone army. This army recognise pathogen-infected cells and cancer cells and kills them. The cells then form a long lasting immune memory to protect the body from future attack
What is a B cell
B cells are special weapon trained forces. These adaptive immune cells internalise and process antigens from specific threats. They signal and interact with T cells. Before producing antibodies which bind to these threats and target them for destruction
