The Immune System: An Introduction

1. Introduction:

The ability to fight against infections is confined to specially evolved immune cells such as B-lymphocytes that are destined to produce immunoglubulins also known as antibodies. Antibodies are proteins that exist in plasma and tissue fluids and they function by interacting with pathogens in order to neutralize them or render them harmless. There are five main types of immunoglobulins namely; IgG, IgM, IgD, IgA and IgE with each playing a unique role in immunity.

2. Assessment of the Immune System:

The assessment of the immune system can be divided into two main types; the innate and the acquired immunity. Innate immunity is an inborn resistance to infections that everyone is born with. It is further divided into two types; natural and artificial. Natural immunity is the one that we are born with such as the skin which provides a physical barrier to infection. Artificial immunity, on the other hand, is the one that we acquire through vaccination. Acquired immunity, on the other hand, is the one that we acquire after being infected by a pathogen or through vaccination. It is further subdivided into active and passive immunity. Active immunity is when our bodies produce antibodies to fight a particular infection while passive immunity is when we receive antibodies from another source such as from mothers to babies or from blood transfusions.

3. The Immune System in PNI 2:

PNI 2 is an immunosuppressive drug that is used to prevent organ transplant rejection and to treat autoimmune diseases such as rheumatoid arthritis, Crohn’s disease, and psoriasis. It works by inhibiting the movement of T-cells which are responsible for attacking transplanted organs and tissues. PNI 2 is a very effective drug; however, it can cause some serious side effects such as an increased risk of infections, kidney damage, and liver damage.

4. Conclusion:

The immune system is a very complex and important system in our bodies. It is responsible for protecting us from diseases and infections. However, sometimes it can be difficult to assess the immune system as there are many different types of immunity. PNI 2 is a very effective immunosuppressive drug; however, it can cause some serious side effects.

There are several ways to assess the strength of someone's immune system: -A blood test can measure the levels of white blood cells, which are a key part of the immune response. -A skin test can measure the body's ability to produce antibodies in response to an antigen.
