RIP Dr Ronald Schultz ❤️

Immunological memory is the ability of the immune system to quickly and specifically recognize an antigen that the body has previously encountered and initiate a corresponding immune response. Generally these are secondary, tertiary and other subsequent immune responses to the same antigen. Immunological memory is responsible for the adaptive component of the immune system, special T and B cells — the so-called memory T and B cells.

.

IgG antibodies are Y-shaped protein molecules that are produced by special white blood cells (B lymphocytes) in response to foreign substances (antigens) such as viruses or bacteria. Antibodies can attach to these viruses or bacteria, rendering them harmless and unable to penetrate healthy cells. They GO AWAY with time and could fall to a NEGATIVE level DOESN'T mean susceptible.

.

Total immunity against viral diseases includes:

1. Local IgA and IgM

2. Humoral immunity of IgG antibodies, both those present in the blood AND those that can be produced quickly when the antigen is present

3. Cellular immunity or MEMORY

4. Other mechanisms.

When we measure antibody titers, we are ONLY documenting the IgG antibodies present in the bloodstream.

.

The Immune System fires up when a pathogen, like a virus, enters the body. The pathogen releases a protein called an antigen, which calls into action the immune system’s special disease-fighting cells. "Called B and T lymphocytes", these cells NOT only destroy the virus, but they REMEMBER what it looked like so they can fend it off in the FUTURE.

.

IMMUNOLOGIC MEMORY allows the immune system to REMEMBER the antigens or organisms to which it has previously been exposed. MEMORY EFFECTOR B cells (long-lived plasma cells) and MEMORY T-cells specific to a virus, give long-term immunity against these diseases.

.

ADAPTIVE IMMUNITY.

.

The “Adaptive Immune Response" is younger than the “Innate Immune Response" in evolutionary terms and is more specific and considerably MORE POTENT in its effects.

.

The constituents of the adaptive immune response are the lymphoid cells. These include:

.

The T lymphocytes and the cytokine and chemokine messenger proteins released by these cells, which direct and REGULATE the adaptive immune response.

.

The B lymphocytes, which transform to the late-stage plasma cells that produce and secrete antibody.

.

The lymphoid cells of the adaptive immune response reside in, and circulate between, the various lymphoid tissues of the body (e.g. the lymph nodes, spleen and mucosal lymphoid tissues). In the adaptive immune response, antigen is first transported from a site of infection by a dendritic cell to the regional lymphoid tissue. That dendritic cell in turn activates "Antigen-Specific T lymphocytes," which further activate Antigen-Specific B lymphocytes.”

.

These activated, Antigen-Specific lymphocytes must then be mobilized from the regional lymphoid tissue and sent to the site of infection, a process that involves these cells moving into the lymphatic and blood circulation and interacting with the endothelial lining of blood vessels.

.

Once these cells reach the site of infection, they are able to mount a full-scale ‘EFFECTOR’ response, which is considerably STRONGER than that permitted by innate immunity. As these processes take some time to occur (in the order of 4–7 days), there is a delay before adaptive immunity ‘takes over’ from the innate form of defence.

.

The final component of Adaptive Immunity is the development of a “REGULATORY RESPONSE" that will "SWITCH OFF" the system when it is NO LONGER REQUIRED (i.e. when the pathogen has been ELIMINATED) so as NOT to cause DAMAGE to normal body tissue.

.

HOWEVER, once this is achieved, the immune system retains the “MEMORY” of that immune response.

IMMUNOLOGICAL MEMORY is another key feature of the Adaptive Immune Response. MEMORY allows the generation of a much MORE effective SECONDARY IMMUNE RESPONSE (Anamnestic MEMORY Response) if that same antigen is EVER RE-ENCOUNTERED.

Could you use raw goat milk to make kefir and give that to dog?
