The Mechanism Behind Affinity Maturation
Somatic Hypermutation: Following preliminary exposure to an antigen, B cells proliferate and introduce random mutations into their antibody genes.
Selection Pressure: Antibodies with upper binding affinities are preferentially selected for expansion.
Clonal Expansion: The particular excessive-affinity B cells proliferate further, bettering the total great of antibodies produced.
Why Is Affinity Maturation Important?
High-affinity antibodies are needed for a great number of programs:
- Enhancing healing efficacy
- Reducing required dosages
- Minimizing facet effects
