What cells produce antibodies and destroy pathogens?
B cells are the cells that produce antibodies, which are proteins that can neutralize pathogens. Natural killer (NK) cells are a type of lymphocyte that can directly destroy infected cells and cancer cells.
Are interferon's viruses?
Interferons are not viruses. They are a group of signaling proteins released by cells in response to the presence of pathogens like viruses. Interferons help to regulate the immune response and inhibit viral replication within infected cells.
How do the immune cells discover intracellular pathogens?
All cells have specialized proteins on their surface that show a sampling of the contents of the cell to certain immune cells, which recognize these samples as self or foreign (i.e. intracellular pathogens) and kill infected cells.
Where do antibodies, the proteins that help the immune system identify and neutralize harmful pathogens, originate from?
Antibodies, the proteins that aid the immune system in recognizing and fighting off harmful pathogens, are produced by specialized white blood cells called B cells.
What is the role of opsonins?
Opsonins are proteins that enhance phagocytosis by labeling pathogens for destruction by immune cells. They do this by binding to pathogens and marking them for recognition and uptake by phagocytic cells like macrophages and neutrophils.
What is attached to surface of pathogens?
Pathogens typically have various structures attached to their surfaces, such as proteins, carbohydrates, and lipids, which can include adhesins, pili, and fimbriae. These components help pathogens adhere to host cells, evade the immune system, and facilitate infection. Additionally, some pathogens possess surface antigens that can trigger immune responses, while others may have protective capsules to enhance their virulence.
Which term describes a group of proteins that combine with antibodies to dissolve pathogens?
The term that describes a group of proteins that combine with antibodies to dissolve pathogens is "complement." The complement system is part of the immune response and consists of a series of proteins that enhance the ability of antibodies and phagocytic cells to clear pathogens from an organism. By binding to antibodies, complement proteins can trigger a cascade of reactions that lead to the destruction of pathogens.
What occurs when pathogens invade the body and what is the response of the body to the invasion?
It depends what sort of pathogen it is and what cells are infected but in general the infected cell is destroyed by lymphocytes and then engulfed by a phagocyte to get rid of what is left.
Why is it good for your immune cells to destroy your infected cells?
It is beneficial for immune cells to destroy infected cells because this process helps contain and eliminate the spread of pathogens, such as viruses and bacteria, within the body. By targeting and destroying these infected cells, immune cells prevent the replication of pathogens and reduce the overall infection load. This mechanism is crucial for maintaining overall health and facilitating recovery, as it allows the immune system to clear infections more effectively and restore homeostasis.
May destroy infected cells select one a cytotoxic t cells b helper t cells c b cells d allergens e phagocytic cells?
a) Cytotoxic T cells are responsible for identifying and destroying infected cells by releasing toxic chemicals that induce cell death. Helper T cells aid in coordinating the immune response by activating other immune cells. B cells produce antibodies that can neutralize pathogens. Allergens are substances that can trigger allergic reactions. Phagocytic cells, such as macrophages, engulf and digest pathogens or infected cells.
Specialized globular proteins that attack foreign proteins and pathogens is known as what?
Antibodies are the specialized globular proteins that specifically bind to foreign proteins and pathogens to aid in their neutralization or elimination from the body. They are produced by white blood cells called B cells as part of the immune response.
What type of proteins do white blood cells make to signal that new pathogens have entered the body?
antibody
