The two categories are granulocytes and agranulocytes. Granulocytes have visible cytoplasmic granules. Examples of granulocytes include neutrophils, eosinophils, and basophils. Agranulocytes have no visible cytoplasmic granules. Eamples of agranulocytes include lymphocytes and monocytes.
How are antigens removed from bacteria?
Macrophages ( in the lymph nodes ) act like phagocytes to engulf and digest the pathogen. But they do not fully digest it. They separate out the antigens and incorporate them into a cell surface molecule. This is exposed on the surface of the macrophage, which becomes known as an antigen-presenting cell. Its function is to find the lymphocytes that can neutralise that particular antigen.

Inflammaging, straight out of my textbook.
My guess would be that if you have been under treatment for RA for 25+ years you would not be a stranger to steroidal anti inflammatory like prednisone or disease modifying drugs such as Methotrexate or Plaquinil, The use of Both of these medications can lead to a lowering of Lymphocytes. I have added a link to the related links below ( How to Understand What Causes a Low Lymphocyte Count ) to aid you in getting a better understanding of this situation. However what it boils down too is that the methods used to fight the inflammation that does the damage in RA is to interfere with the immune system to a degree where inflammation is reduced and this can lead to other imbalances.

Opsonization involves an antibody binding to a pathogen itself while neutralizing invovles an antibody binding to a toxin, AKA something the pathogen produces.
What is an antigen and how does the immune system use them?
Antigens are majorly organic molecules which are not familiar to the organism itself. and starts immune response.
What does pathogens and microbes have in common?
Microbes is a more global term for small living creatures. Some have negative impact on our system when they intrude our body, called pathogens. They interfere with reactions in our body.
