Immune System

Vitamin C acts as a stimulant in the body's immune system by supporting the production of white blood cells, which help fight off infections and illnesses. It also acts as an antioxidant, protecting cells from damage and promoting overall health.

Yes, pumped breast milk contains antibodies that can help boost a baby's immune system.

Well, honey, a lymphocyte abs in a blood test simply refers to the absolute count of lymphocytes in your blood. These are a type of white blood cell that helps your body fight off infections and diseases. So, if your lymphocyte abs levels are off, it could be a sign that your immune system is working overtime or maybe taking a little nap.

Firmicutes is a phylum of bacteria that includes several pathogenic genera. Notable pathogens within this group include Staphylococcus (e.g., Staphylococcus aureus, which can cause skin infections and food poisoning) and Streptococcus (e.g., Streptococcus pneumoniae, responsible for pneumonia and meningitis). Other significant pathogens include Clostridium species, such as Clostridium difficile, which can lead to severe gastrointestinal issues. These bacteria can be found in various environments and are often part of the normal microbiota but can become harmful under certain conditions.

Primary immune cells are the key components of the immune system responsible for recognizing and responding to pathogens. These include lymphocytes such as B cells and T cells, which are crucial for adaptive immunity, as well as innate immune cells like macrophages, dendritic cells, and natural killer (NK) cells. Together, they work to detect, target, and eliminate foreign invaders, playing vital roles in both immediate and long-term immune responses. Their coordinated actions help maintain the body's defense against infections and diseases.

Invading antigens, such as bacteria and viruses, are primarily targeted and consumed by a type of white blood cell known as phagocytes. Macrophages and neutrophils are key phagocytes that recognize, engulf, and digest these foreign substances through a process called phagocytosis. Additionally, dendritic cells play a role in capturing antigens and presenting them to other immune cells to initiate a broader immune response. Together, these cells help protect the body from infections and maintain immune system health.

One study performed in 1973 showed that white blood cells from individuals who had consumed 100 grams of sugar (about 20 teaspoons) were less active. This study has been cited for many years as evidence that sugar suppresses the immune system, by no less than the famous pediatrician Dr. Sears.

However, no studies have since proven that individuals who consume more sugar actually get more colds or flu. The way the body fights disease is extremely complex and the effects of sugar consumption on the immune system have not been definitively identified. The scientific consensus seems to be that eating a healthy, balanced diet and maintaining normal weight is the best way to sustain overall well-being, including reducing susceptibility to illness. There is little to no evidence that eating a candy bar or drinking a Coke will cause you to be acutely susceptible to disease.

are you asking 'what is the chronic inflammatory disease in which the immune system attacks the myelin sheath of nerve cell axions?

if that is your question, the answer is Multiple Sclerosis.

The immune system detects antigens which can be proteins, lipids, or carbohydrates displayed on the surface of cells. In terms of membrane proteins, the immune system detects antigens presented by major histocompatibility complex (MHC) proteins on the surface of cells to distinguish between self and non-self molecules.

Cytotoxic T cells are a type of cell that destroys body cells infected with microbes. They recognize infected cells by detecting specific antigens on their surface and then release toxic substances to kill the infected cell.

Yes. Most biological catalysts are called enzymes.

A catalyst (and so enzymes) reduce the activation energy. In many cases this means a lower temperature is needed for a reaction to work.

No. Almost all bacteria are not. There are bacteria everywhere performing essential functions like breaking down dead animals and plants. Bacteria are essential to health helping digest food and preventing pathogenic bacteria from getting out of control.

Non-pathogenic diseases are conditions that do not result from an infectious agent (such as bacteria, viruses, or parasites) and do not cause harm to the host. These diseases may be genetic, autoimmune, or related to environmental factors, but they do not involve the invasion or colonization of the body by harmful microorganisms.

Major Histocompatibility Complex (MHC) molecules are located on the cell surface of a cell. They are expressed on the plasma membrane, presenting peptides to T cells for immune recognition and response.

Non-pathogenic organisms are not harmful to humans and do not cause disease. Some non-pathogenic bacteria can even be beneficial, such as those found in the gut that aid in digestion.

The cell membrane supervises the substances entering and exiting the cell. It is selectively permeable and regulates the passage of molecules in and out of the cell through active or passive transport mechanisms.

Proteins are especially important because they serve a wide range of functions in the body, including cell signaling, immune response, and as catalysts for enzyme activity. Their diverse roles make them vital for maintaining proper physiological functions and processes.

When the immune system is compromised, it loses some of its ability to function properly. It is almost like running on a sprained ankle that is not completely healed. The more damaged the immune system is, the less function it has.

Mononucleosis is caused from the virus known as the Epstein-Barr virus and is

commonly referred as "the kissing disease". In healthy individuals it is most usually beaten by bed rest, along with adequate amount of fluid intake. The

human immune system, if not compromised by fatigue, dehydration or vitamin deficiency will most often win out. Therefore the patient should be well rested while drinking water and fruit juices, along with taking vitamin supplements, such as high doses of vitamin C and a good B complex including, Folic Acid and Vitamins B12 B6 and care should be taken to monitor fever. If fever rises above 101.5 F then consider recommended doses of acetaminophen or ibuprofen, along with sponge bath. If patient is immuno-compromised then care in an ICU would be indicated.

Stem cell therapy for hair has shown promising results in promoting hair growth and treating hair loss. However, like any medical procedure, there can be potential risks and side effects. It is important to consult with a qualified healthcare provider to discuss the safety and potential benefits of stem cell therapy for hair in your specific case.

Natural killer (NK) cells are nonspecific lymphocytes that play a crucial role in killing tumor cells and virus-infected cells. They are part of the innate immune system and can quickly identify and destroy abnormal cells without the need for prior exposure.

"B cells" are named after the Bursa of Fabricius where they were first discovered in birds. The Bursa of Fabricius is an organ in birds that is involved in the development of B cells. The "B" stands for "bursa-dependent" in reference to this organ.

If anti-B antibodies (from someone who is blood type A or AB) are mixed with group B red cells, agglutination or clumping of red cells will occur due to a reaction between the antibodies and the B antigen on the red cells. This can lead to transfusion reactions if incompatible blood is transfused, causing harm to the recipient.
