Bacteria and other foreign invaders are attacked by the immune system via special proteins called antibodies. They work by binding on to corresponding sites on the pathogen called antigens. This works to neutralise the invaders by blocking its glycoproteins and marking it for destruction by macrophage white blood cells. Some larger antibodies can bind multiple pathogens together in a process called agglutination.
Exposure to a disease-causing organism typically results in acquired immunity, either through natural infection or vaccination. This type of immunity is specific to that particular organism and provides protection against future encounters with the same pathogen.
Yes, it is possible to get Lyme disease more than once if you are bitten by an infected tick on separate occasions. This is because the initial infection may not provide complete immunity to future infections. It is important to take precautions to prevent tick bites, especially in areas where Lyme disease is common.
Acquired immunity is developed by the body after exposure to a pathogen or vaccine, leading to the production of antibodies. Passive immunity is temporary protection acquired through the transfer of pre-formed antibodies, such as from mother to child during pregnancy or through receiving injections of antibodies.
Langerhans cells are epidermal cells that play a key role in immunity and disease resistance. They act as antigen-presenting cells, initiating immune responses in the skin by capturing and processing antigens to activate T cells.
Herd immunity is associated with vaccinaton. For the entire population to be protected a certain percentage has to be vaccinated (the pecentage varies for different diseases). This protects those who cannot have vaccines such as those allergic to eggs or those on immunosuppresants (excuse the spelling!).
