Thymus-independentB cells are most likely to make antibodies that bind to ______ antigens.1 pointviralselfplantfungalbacterial

Thymus-independent B cells primarily respond to antigens that do not require T cell help for activation. They are particularly effective against repetitive structural components found in certain organisms. The types of antigens that are most commonly associated with thymus-independent B cells are typically polysaccharide capsular antigens found on bacteria and fungi.

Given the options:

1. Viral - Most viruses require T cell help for B cell activation.
2. Self - These are usually recognized by T cells and are involved in autoimmunity rather than thymus-independent activation.
3. Plant - Not a typical response for thymus-independent B cells.
4. Fungal - Similar to bacterial antigens but less commonly tested.
5. Bacterial - This is the most relevant answer as many bacterial polysaccharides can induce a response from thymus-independent B cells.

Final Answer

Bacterial antigens.
