destruida con formalina. Se prepararon células B específicas de antígeno a<br />
partir de esplenocitos mediante la unión de células CD43+ a placas de Petri<br />
recubiertas con anticuerpo anti-CD43 para eliminar las células T, y las células<br />
no unidas se pasaron a través de una columna de lana de nailon para<br />
deplecionar las células accesorias. Las células retenidas se recogieron y se<br />
unieron a placas de Petri recubiertas con A. actinomycetemcomitans para<br />
enriquecer las células B unidas a A. actinomycetemcomitans (AAB, A. actinomycetemcomitans-binding<br />
B cells). También se recogieron las células B<br />
no unidas a A. actinomycetemcomitans (ANB, A. actinomycetemcomitansnon<br />
binding B cells) y las células B de los ratones donantes no inmunizados<br />
(NIB, non-immunized B cells). Cada tipo de célula B se inyectó en un grupo<br />
de ratones receptores, que fueron infectadas por vía oral con A. actinomycetemcomitans<br />
viable.<br />
Al final, los valores de anticuerpos contra A. actinomycetemcomitans en<br />
suero y líquido crevicular fueron significativamente mayores en los ratones<br />
receptores a los que se les transfirió AAB en comparación con los<br />
ratones receptores a los que se les transfirió ANB o NIB. Se observó un<br />
número notablemente elevado de células formadoras de anticuerpos en el<br />
bazo de los ratones receptores con AAB, y estos ratones también mostraron<br />
una resorción ósea significativamente elevada en comparación con los otros<br />
grupos. Estos resultados sugieren que las células B pueden contribuir a la<br />
resorción ósea periodontal y que para que ésto se produzca se necesita<br />
la estimulación antigénica de las células B.<br />
Kawai et al. (2007) examinaron si la inducción de una respuesta inmunitaria<br />
adaptativa contra la colonización oral de Pasteurella pneumotropica no<br />
patogénica, mediante la inmunización con la bacteria estrechamente relacionada<br />
desde el punto de vista filogenético A. actinomycetemcomitans, podría<br />
provocar una pérdida de hueso periodontal en ratones. La inducción de esta<br />
respuesta adaptativa provocaba una pérdida de hueso periodontal dependiente<br />
del RANKL en los ratones.<br />
