What are the differences between the classical and alternative pathways in the context of immune response activation?
The classical pathway is part of the innate immune response and is activated by specific molecules on pathogens. The alternative pathway is also part of the innate immune response but is activated by different molecules. Both pathways lead to the activation of the complement system, which helps to eliminate pathogens from the body.
What is the immune response mediated by naive lymphocytes that occurs on first exposure to antigens?
The pattern recognition receptors check for pathogen patterns, which decides if the innate immune system should be activated.
Are toll-like receptors considered part of the innate immune system or the adaptive immune system?
Toll-like receptors are part of the innate immune system.
Are neutrophils an innate immune cell?
No
What is an innate immune cell?
Neutrophil
Is the innate immune system selective?
no
What are the key differences between the classical pathway and the alternative pathway in the immune response?
The classical pathway is part of the adaptive immune response and is triggered by specific antibodies binding to pathogens. The alternative pathway is part of the innate immune response and is activated by the presence of foreign substances on the surface of pathogens.
What are the antibodies of the innate immune system?
The innate immunes system does not produce any antibodies. Cells of the innate immune system are macrophages, granulocytes (neutrophils, basophils, eusinophils), natural killer cells...
Difference between innate and acquired immunity?
The way in which inherited and acquired immunities differ is in the way the immune system responds to infection. With inherited immunity, the body does not create antibodies that are particular to a specific pathogen unlike acquired immunity.
What is not a part of the innate immune defenses?
which of these is not apart of the body immune system
How do cells involved in the innate immune response detect the presence of pathogens?
Cells involved in the innate immune response detect the presence of pathogens through pattern recognition receptors (PRRs) that recognize specific molecular patterns commonly found on pathogens, known as pathogen-associated molecular patterns (PAMPs). When a PRR on a cell binds to a PAMP, it triggers a signaling cascade that leads to the activation of the innate immune response, including the production of inflammatory mediators and recruitment of other immune cells to the site of infection.
What occurs when the innate immune system is attempting to flush a specific area with phagocytes?
When the innate immune system is attempting to flush a specific area with phagocytes, it initiates an inflammatory response. This response involves the release of chemical signals that attract phagocytes to the site of infection or injury. The phagocytes then engulf and destroy pathogens, helping to eliminate the threat.
