Neutrophils are generally not the primary immune cells involved in allergic responses; instead, eosinophils and mast cells play a more significant role. During an allergic reaction, the body produces IgE antibodies that trigger the release of histamine and other mediators, which primarily attract eosinophils. However, in certain cases of allergic reactions, such as those with secondary infections or inflammation, neutrophils may be elevated, but this is not typical of the classic allergic response.

Which White Blood Cells occur first Neutrophils or Basaphils?
Neutrophils are the first white blood cells to respond during an infection or inflammation. They are the most abundant type of white blood cell and play a crucial role in the innate immune response. Basophils, on the other hand, are a type of white blood cell involved in allergic reactions and inflammation, but they are not typically the first responders.
Can bronchitis cause high neurophils?
Yes, bronchitis can lead to an increase in neutrophils, as it is often associated with inflammation and infection in the airways. During bronchitis, the immune system responds to the infection or irritation by mobilizing neutrophils to the affected area, resulting in elevated levels in the blood. This response is part of the body's effort to combat the underlying cause of bronchitis, whether viral or bacterial.
What is significance of band cells present in blood?
Band cells are immature white blood cells typically found in the blood during an infection or inflammation. Their presence often indicates an ongoing immune response. Elevated levels of band cells may suggest an acute infection or a stress response in the body. Monitoring band cell levels can help healthcare providers assess the severity of an infection or inflammatory condition.
What is the chemical called that causes an allergic response?
It's general biochemical name is an Antigen - anti = against and gen = genesis.
Is heparin released in response to an allergic reaction.?
Heparin is not released in response to an allergic reaction; rather, it is a naturally occurring anticoagulant produced by mast cells and basophils. During an allergic reaction, these cells release histamine and other mediators, but heparin's role is primarily related to inhibiting blood clotting. While heparin can be involved in some inflammatory responses, it is not a direct mediator of allergic reactions.
What is the main bacteria killer during infections?

The body's defense system literally eats invading pathogens during what response?
The body's defense system literally eats invading pathogens during the immune response known as phagocytosis. In this process, specialized white blood cells called phagocytes, such as macrophages and neutrophils, engulf and digest harmful microorganisms and debris. This mechanism is a crucial part of the innate immune response, helping to eliminate infections and maintain overall health.
Is neutrophils an antigen presenting cell?
Neutrophils are primarily known as phagocytic cells that play a key role in the innate immune response, but they are not considered classical antigen-presenting cells (APCs) like dendritic cells, macrophages, or B cells. However, neutrophils can exhibit some antigen-presenting capabilities, especially during inflammatory responses, by processing and presenting antigens to T cells. This function is not their primary role, and their effectiveness as APCs is generally lower compared to specialized APCs.
What helps to localize and contain the foreign material during an inflammatory response?
During an inflammatory response, neutrophils and macrophages work to "wall off" and contain the foreign material. This is done through the formation of granulomas, fibrosis, and encapsulation to prevent the spread of infection or damage to surrounding tissues. Additionally, the body may initiate the process of phagocytosis to engulf and remove the foreign material.
