Cytokines can help induce the maturation of immature T and B cells. Naïve B cells in the spleen or lymph nodes can be activated in a few different ways, but typically need a more than one step to differentiate into plasma cells that secrete antibodies against a specific antigen and therefo...
This system was able to reproduce the organization of B and T lymphocytes into 3D functional aggregates that matured into plasma cells producing antibodies in response to influenza vaccination. Cells from multiple human donors were then introduced into the chip and were able to produce antibodies. ...
Antibodies are generated in immune reactions, mostly in secondary lymphoid organs, when activated B lymphocytes are instructed to differentiate into antibody-secreting plasmablasts. These can then leave the secondary lymphoid organs, migrate to the bone marrow and there become (longlived) plasma cells4...
A person with blood type A has: a. B antigens on the red blood cells b. A antibodies in the plasma c. A antigens on the red blood cells d. Rh antigen on the red blood cells e. A and B antibodies in...
plasma and urine. While these effects are promising, it should be noted that these observations provide little insight into the true mechanisms of action given that MSCs can modulate the joint microenvironment through interactions with a variety of cell types within the joint, including chondrocytes ...

What is the substance that evokes the production of antibodies? What do you call the type of viral replication cycle resulting in the release of new viruses by lysis (breaking open) of the host cell? What are the viral effects on the ...
and seek out a specific virus or bacterium to tag it for destruction by white blood cells. These antibodies are so effective that they can be harvested in the plasma of people who have recovered from a disease in order to passively protect people who can’t make enough antibody on their ...
Intravenous immunoglobulin (IVIG) preparations comprise pooled IgG antibodies from the serum of thousands of donors and were initially used as an IgG replacement therapy in immunocompromised patients. Since the discovery, more than 30 years ago, that IVIG therapy can ameliorate immune thrombocytopenia, ...
Naive B cells express a surface BCR, which allows B cells to recognize antigens and to initiate B-cell activation and expansion, which eventually results in the generation of memory B cells and antibody-secreting plasma cells. The BCRs (such as the secreted BCRs, which are the antibodies/...
