    • Los LOS Neisseria Tfh reconocen y se unen al AL Amyloidosis complejo antígeno-CMH II.
    • Luego, los LOS Neisseria Tfh expresan el ligando CD40 CD40 Members of the tumor necrosis factor receptor superfamily with specificity for CD40 ligand. They are found on mature B-lymphocytes, some epithelial cells; and lymphoid dendritic cells. Evidence suggests that CD40-dependent activation of B-cells is important for generation of memory B-cells within the germinal centers. Mutations in the CD40 antigen gene result in hyper-igm immunodeficiency syndrome, type 3. Signaling of the receptor occurs through its association with tnf receptor-associated factors.

Maduración y Diferenciación de Linfocitos B

Maduración de la afinidad

• Mientras que el linfocito B se ha activado, se llevan a cabo procesos en la zona oscura del centro germinal para “ajustar” aún más la afinidad del anticuerpo por el antígeno.
• La maduración por afinidad es el mecanismo por el cual los LOS Neisseria linfocitos B, después de una estimulación repetida, aumentan su afinidad por un antígeno específico que se les presenta.
• La hipermutación somática facilita el aumento de la afinidad:
  • Una mutación programada que involucra las regiones variables de los LOS Neisseria genes Genes A category of nucleic acid sequences that function as units of heredity and which code for the basic instructions for the development, reproduction, and maintenance of organisms.

• Selección:
  • Después de la mutación, los LOS Neisseria linfocitos B con receptor Receptor Receptors are proteins located either on the surface of or within a cell that can bind to signaling molecules known as ligands (e.g., hormones) and cause some type of response within the cell. Receptors de linfocitos B de alta afinidad ahora se mueven a la zona clara y acceden al AL Amyloidosis antígeno presentado por las células dendríticas foliculares.
    • Alta afinidad con el antígeno → es más probable que se seleccionen para presentar y recibir señales de supervivencia de los LOS Neisseria Tfh
    • Los LOS Neisseria linfocitos B con menor afinidad no recibirán señales de supervivencia y morirán por apoptosis Apoptosis A regulated cell death mechanism characterized by distinctive morphologic changes in the nucleus and cytoplasm, including the endonucleolytic cleavage of genomic DNA, at regularly spaced, internucleosomal sites, I.e., DNA fragmentation. It is genetically-programmed and serves as a balance to mitosis in regulating the size of animal tissues and in mediating pathologic processes associated with tumor growth. Ischemic Cell Damage.
• Este proceso no solo permite la diversidad, sino que también permite que solo los LOS Neisseria linfocitos B más optimizados sobrevivan y se diferencien.

Recombinación de cambio de clase

• Los LOS Neisseria linfocitos B supervivientes (con alta afinidad por el antígeno) luego se someten a un cambio de clase, un paso que también requiere desaminasa de citidina inducida por activación.
