Imunidade humoral

Imunidade humoral é uma subdivisão da imunidade adquirida onde a resposta imunológica é realizada por anticorpos. Estes anticorpos são secretados por plasmócitos (células derivadas dos linfócitos B) após detectarem a presença de antígenos, ou após serem estimulados por meio de citocinas liberadas pelos linfócitos T.[1]

É importante no combate a micro-organismos e pode ainda haver participação de mastócitos/basófilos, com eliminação de grânulos contendo substâncias com atividade microbicida.

Tipos de imunidade humoral:

Ativa natural: adquirida através de doença clínica ou sub-clínica

Ativa artificial: adquirida por meio de vacinas

Passiva natural: passagem de IgG por meio da placenta (congênita)

Passiva artificial: passagem de anticorpos prontos (Ex. soro antitetânico)

Classes

A imunidade humoral possui 5 classes.

Ver artigo principal: Imunoglobulinas
  • A IgM que tem a resposta imune primária, alto peso molecular, restrita ao espaço intra-vascular e faz a defesa no sangue.
  • A IgD que é o BCR no linfócito B.

Darwinismo sociale

Questa voce o sezione sull'argomento politica è ritenuta da controllare. Motivo: questa voce è praticamente ricerca originale, anzi peggio, sembra una tesina di scuola superiore. Molte fonti sono usate in modo scorretto per appoggiare pareri personali di chi scrive, quando invece esse dovrebbero essere funzionali alla voce. Tradurre a pappagallo una voce dal francese, che è ambigua e polarizzata politicamente e culturalmente, ha fatto di questa voce qualcosa di confusionario e poco d...
