Lymphokines do not attack macrophages. Lymphokines are molecules released by activated T cells to regulate the immune response, while macrophages are immune cells that engulf and digest pathogens. However, some lymphokines can stimulate macrophages to be more effective in phagocytosis and killing of pathogens.

Which white blood cells turn into macrophages in tissue?
Monocytes are white blood cells that can migrate from the bloodstream into tissues where they differentiate into macrophages. Once in the tissue, monocytes mature into tissue-resident macrophages and play a crucial role in immune responses, inflammation, and tissue repair.
Red blood cells are called macrophages true or false?
False. Red blood cells are not called macrophages. Macrophages are a type of white blood cell that helps to recognize, engulf, and destroy pathogens and foreign substances in the body.
Are highly phagocytic cells that are a part of the body's defense system These cells can be localized or they can wander throughout the body?
These cells are called macrophages. They play a key role in engulfing and digesting pathogens and debris in the body. Macrophages reside in specific tissues or circulate in the blood to different parts of the body to carry out their immune functions.
What is the importance of macrophages?
Macrophages play a crucial role in the immune system by engulfing and digesting pathogens, dead cells, and other harmful substances. They also help initiate an immune response by presenting antigens to other immune cells. Additionally, macrophages contribute to tissue repair and maintenance.
What are the functions of macrophages?
Macrophages play a key role in the immune system by engulfing and digesting pathogens, dead cells, and cellular debris. They also present antigens to activate other immune cells, produce inflammatory mediators, and contribute to tissue repair and remodeling. Overall, macrophages serve to promote immune responses, maintain tissue homeostasis, and participate in various physiological processes.
Macrophages are attracted to the infected site and are prepared to attack the invaders by what?
Lymphokines
What type of white blood cells attack specific microorganisms?
Macrophages
Neutrophils and macrophages are capable of ingesting bacteria?
Neutrophils and macrophages attack and destroy bacteria. Neutrophils are mature cells that can ingest bacteria. Macrophages enter tissues and swell ingesting bacteria that is in the tissues and blood stream.
What are the functions of lymphokine?
Lymphokines are a type of cytokine produced by activated lymphocytes. They play a role in regulating immune responses by influencing the behavior of other immune cells. Lymphokines can help coordinate the body's defense against infections and other threats by promoting inflammation, activating immune cells, and regulating immune responses.
How can you kill viruses?
There are numerous products that kill viruses on environmental surfaces, but few that safely attack them in the body. The body's "T helper cells" can signal macrophages to attack some viruses.
What directs the immune response by signaling between the immune systems?
lymphokines
What are monokines and lymphokines?
There is a general term called cytokines. These are secreted molecules with autocrine (self taget), paracrine (local target), and endocrine (far target) functions. These chemicals can be used to alter behavior of a cell (vasoactivate endothelial cells to leak out plasma), commit a cell to apoptosis (cytotoxic), or attract cells form the adaptive and innate immune system to perform a function (chemotaxis). Lymphokines are a subclass of cytokines which are released by cells of the lymphoid progenitor (b-cells, t-cells, and NK cells). Monokines are a subclass of cytokines which are sercreted by monocytes and macropohages. Macrophages are mature Monocytes which are made from a myeloid progenitor.
How do macrophages replicate?
Macrophages do not replicate. The bone marrow produces Monocytes which when they find a damaged area transform into Macrophages.
Chemicals released by sensitized t lymphocytes to keep us healthy are known as?
lymphokines
What directs the antigen-antibody response by signaling between the cells of the immune system?
Lymphokines
Which organ does NOT contain fixed macrophages?
The brain does not contain fixed macrophages. Instead, microglia serve as the resident macrophages in the brain.
Are macrophages responsible for allergic reactions?
No, macrophages are responsible for removing dying or dead cells in the early stages of inflammation. Macrophages essentially ingest these.
