Immune System

Pathogens can increase their virulence through genetic mutations, acquisition of new virulence factors, suppression of host immune responses, or improved adaptation to host environment. This may result in enhanced ability to invade host tissues, evade immune detection, or cause more severe disease.

You Must mean White blood cells.

White blood cells kill bacteria by first engulfing them, this process i believe is called

phagocytocis. They literally eat the bacteria and digest it.

Yes, MHC class I proteins are found on most nucleated cells in the body. They play a key role in presenting endogenous antigens to cytotoxic T cells for immune surveillance and response.

Mediators of humoral immunity include antibodies, which are produced by B cells and circulate in the bloodstream. These antibodies can recognize and bind to specific antigens, marking them for destruction by other immune cells. In addition, cytokines released by activated B cells and helper T cells help regulate the immune response and stimulate antibody production.

T cell response is critical for immune defense against infections and cancer. However, dysregulation of T cell responses can lead to autoimmune diseases or hypersensitivity reactions. Modulation of T cell responses is an important target for therapeutic interventions in various diseases.

Interferons are cytokines that can enhance the activity of B cells and T cells while also enhancing nonspecific defense mechanisms in the body. Interferons help regulate the immune response against viruses and other pathogens by activating macrophages and natural killer cells.

A pathogen can enter a new reservoir through various routes, such as direct contact with infected animals or consumption of contaminated food or water. Once in the new reservoir, the pathogen may adapt to the new host species and establish infection cycles within that population.

IgG antibodies account for the bulk of circulating antibodies in the blood. They are the most abundant class of antibodies and play a crucial role in providing long-term immunity.

The reasons I'm asking are:

My homeopatic doctor told me when I was young to avoid milk, chocolate, oranges, tomatoes, and apple. I didn't get rid completely of the itching-drying-and-then-painfull blisters until I stopped completely those foods.

Later, I noticed by adding those to my diet, related skin issues (i.e. ate-skin holes filled with liquid which itches when the flesh is eaten, burns when sweating, cracks when liquid dries) appeared in the following locations with different foods.

Milk -> Mouth ulcer

Orange - > Voice, throat

Chocolate -> Finger, digits and sides

Green Onions -> Hand palm, Foot sole. Aggravated by sweating.

Tomato -> Intestins (diverticulosis)

Apple - Bronchi (Asthma symptoms) This aggravated by dust or mold, heavy breathing (e.g. exercise)

Do you know the connection between them and / or natural cure?

CD8+ T lymphocytes, also known as cytotoxic T cells, become cytotoxic when they are activated by presenting antigens on major histocompatibility complex class I molecules. These cells play a key role in the immune response by directly killing infected or abnormal cells.

Soap and warm water help to loosen and remove bacteria from the skin by breaking down oils and dirt that may be harboring the bacteria. Proper handwashing techniques can help to effectively remove bacteria from the skin.

Pathogenic bacteria are those which cause disease. You can identify a link between a bacterium and a disease by isolating the bacterium in a statistically significant number of occurances of the disease. Proving the link is causative is more difficult, but could be done with a cohort study or in vivo experimentation. Probably the most well documented case in recent years is the proving of Helicobacter pylori as a causative agent of stomach ulcers.

Antibodies are produced by B cells, which are a type of white blood cell. When germs enter the body, B cells are activated to produce specific antibodies that can help target and neutralize the invading germs.

Looking for antigens is part of a specific immune response.

Regulatory T cells (Treg) suppress the action of other T cells. This inhibits immune responses to self-antigens, aiming to prevent the immune system from attacking normal self cells.

The body's immune system fights pathogens through multiple mechanisms. These can include engulfing and digesting pathogens (phagocytosis), producing antibodies to neutralize pathogens, releasing signaling molecules to recruit other immune cells, and triggering a process called apoptosis in infected cells to prevent the spread of the infection.

Antigen-presenting cells (APCs) such as dendritic cells bind with antigens and present them to B cells, T cells, and macrophages, leading to their activation. This process is crucial for initiating immune responses against pathogens and foreign substances in the body.

What about a range of 22.2-43.6% as a normal range for lymphocytes, and the number is 47.6%, would this be considered abnormally high?

The plasma cell has some of the best weapons in the game (you just lost the game.) An invader is a highly trained mercenary assassin, knowing that it still cannot defeat a plasma cell. If you think you should be an invader or plasma cell truly choose plasma cell; it is your best bet. Thank-you John f. Kennedy

Bacillus non-pathogenic refers to a strain of Bacillus bacteria that does not cause disease in humans, animals, or plants. These non-pathogenic strains are often used in various industrial processes, such as bioremediation or probiotics, due to their beneficial properties without posing a risk to health.

No, plasma cells develop from B cells after exposure to an antigen. T cells play a role in activating B cells to differentiate into plasma cells and produce antibodies. Plasma cells are responsible for producing large amounts of antibodies specific to the antigen encountered.

A cytotoxic B cell produces antibodies that can directly bind to and kill infected or abnormal cells. These antibodies mark the target cells for destruction by other immune cells, leading to the elimination of the threat.
