<prompt> Utachiona hunokonzera zvirwere hungakundikana sei kupukunyuka mumasero eB? Tichifunga nezvemubvunzo wapfuura, nyora mashoko akapoteredza mhinduro yacho. Inogona kuva mitsara 1 - 20. Mashoko akapoteredza:  <response>: Sero reB rinoziva zvirwere kana maantibody ari pamusoro paro akasunga imwe antigen yokumwe. Iyi antigenantibody complex inotorwa nesero reB uye inoshandurwa neproteolysis kuva peptides. Sero reB rinobva rabudisa maantigenic peptides aya pamadziro aro MHC class II molecules. Mubatanidzwa uyu weMHC neantigen unokwezva T cell yakafanana, iyo inoburitsa ma lymphokine uye inoita kuti B cell iite basa. Sezvo B cell yakaitwa kuti iite basa inobva yatanga kupatsanuka, vana vayo masero eplasma vanobudisa mamiriyoni emakopi eantibody anoziva antigen iyi. Aya masoja anorwisa chirwere anoparadzirwa muplasma yeropa uye lymph, anosunga kumagene anokonzera zvirwere anoratidza antigen uye anoratidza kuti achaparadzwa nokushandiswa kwecomplement kana kuti achatorwa ndokuparadzwa nema phagocyte. Antibodies dzinogonawo kudzivisa zvinetso zvakananga, kupfurikidza nokusunga kune utachiona hunouraya kana kuti kupfurikidza nokupindira nevanogamuchira vanoshandiswa nemavhairasi nemabhakitiriya kutapurira masero.
