Boosting The Innate Arm of Your Immune System

Arm your immune system -

A fever may develop as well. Then the blood vessels expand further and even more immune system cells arrive. Bacteria or viruses that enter the body can be stopped right away by scavenger cells phagocytes.

Scavenger cells are special kinds of white blood cells leukocytes. These cells enclose germs and "digest" them. The remains of these germs move to the surface of the scavenger cells to be detected by the adaptive immune system. There are also other types of immune system cells that release substances to kill bacteria and various germs.

Both germs and body tissue and immune system cells die and decay during an immune system response. Their remains form pus, a yellowish fluid. Several proteins enzymes help the cells of the innate immune system. A total of nine different enzymes activate one another in a process similar to a chain reaction: One enzyme in the first stage alerts several enzymes of the second stage, each of which again activates several enzymes of the third stage, and so on.

This allows immune system responses to escalate very quickly. The natural killer cells are the third major part of the innate immune system.

They specialize in identifying cells that are infected by a virus or that have become tumorous. To do this, they search for cells that have changes in their surface, and then destroy the cell surface using cell toxins.

The adaptive immune system takes over if the innate immune system is not able to destroy the germs. It specifically targets the type of germ that is causing the infection. But to do that it first needs to identify the germ.

This means that it is slower to respond than the innate immune system, but when it does it is more accurate. It also has the advantage of being able to "remember" germs, so the next time a known germ is encountered, the adaptive immune system can respond faster.

The second infection is then usually not even noticed, or is at least milder. T lymphocytes also called T cells are produced in bone marrow and then move to the thymus through the bloodstream, where they mature.

The "T" in their name comes from "thymus. T cells have detection features on their surfaces that can attach to germs — like a lock that one particular key will fit.

The immune system can produce a matching T cell type for each germ in an infection within a few days. Then if a germ attaches to a matching T cell, the T cell starts to multiply — creating more T cells specialized to that germ.

Because only the cells that match the germ multiply, the immune response is customized. B lymphocytes B cells are made in the bone marrow and then mature there to become specialized immune system cells. They take their name from the "B" in "bone marrow.

The B cells are activated by the T helper cells: T helper cells contact B cells that match the same germs that they do. This activates the B cells to multiply and to transform themselves into plasma cells. These plasma cells quickly produce very large amounts of antibodies and release them into the blood.

Because only the B cells that match the attacking germs are activated, only the exact antibodies that are needed will be produced. Some of the activated B cells transform into memory cells and become part of the "memory" of the adaptive immune system.

The various cells of the adaptive immune system communicate either directly or via soluble chemical messengers such as cytokines small proteins. These chemical messengers are mostly proteins and are produced by different cells in the body.

Antibodies are compounds of protein and sugar that circulate in the bloodstream. They are created by the immune system to fight germs and foreign substances.

Antibodies can quickly detect germs and other potentially harmful substances, and then attach to them. This neutralizes the "intruders" and attracts other immune system cells to help. Antibodies are produced by the B lymphocytes.

Germs and other substances that can provoke the creation of antibodies are also referred to as "antigens. An antibody only attaches to an antigen if it matches exactly, like a key in the lock of the antibody. That is how antibodies detect the matching germs to initiate a fast response from the adaptive immune system.

If the immune cells in those lymph nodes are restimulated in the same place, there is a greater immunological response, the study said. Although the study showed a greater immune response, researchers can't say for sure that getting the booster in the same arm results in better or longer-lasting protection, Schaffner said.

The immune cells are important for quickly destroying the virus, but antibodies are also important to prevent further harm, the study said. And researchers did not find a larger number of antibodies. However, the antibodies in people with the booster in the same arm were better at binding to the viral spike proteins, the study showed.

Spike proteins are responsible for the coronavirus entering cells, according to the National Institutes of Health. Questions remain about the actual protection impact, and this study is small, but Schaffner said it is worthwhile to consider the results when going for your next booster.

This study made Schaffner think about this fall when he will get vaccines for respiratory syncytial virus, known as RSV , and influenza as well as a Covid booster.

The study was published recently in The Journal of Clinical Investigation. The new study tested serum samples collected at various times after vaccination. The improved response clearly materialized three weeks after the second booster and persisted beyond 13 months after boosting. Investigators found heightened immunity to the original SARS-CoV-2 strain, and an even stronger immune response to the omicron variant that emerged roughly a year after arm alternation. OHSU had the opportunity to examine the question as part of a series of laboratory studies using blood drawn from willing employees beginning early in the COVID pandemic.
