If a pathogen is able to evade or suppress the actions of T-cells and B-cells, the immune response may not be able to effectively fight the infection. This can lead to several outcomes:
Chronic infection: The pathogen may be able to persist in the body for a long time, causing a chronic infection.
Reoccurring infections: If the immune response is not effective, the individual may experience reoccurring infections with the same pathogen.
Immune evasion: Pathogens may evolve mechanisms to evade the immune response, allowing them to persist and cause ongoing infection.
Immunosuppression: The pathogen may also suppress the immune response, making it harder for the body to fight off other infections.
These are some of the ways that a pathogen can interfere with the function of T-cells and B-cells, leading to a less effective immune response
