Nws txhawb kev loj hlob thiab kev sib txawv ntawm lub cev tiv thaiv kab mob xws li T thiab B lymphocytes, txhim kho kev sib cuam tshuam ntawm cov hlwb, thiab txhim kho lub cev tiv thaiv kab mob. Nyob rau tib lub sijhawm, nws koom nrog kev tswj hwm ntawm lub cev tiv thaiv kab mob hauv lub cev, cuam tshuam rau kev tso tawm thiab kev qhia ntawm cytokines, thiab tswj kev tiv thaiv kab mob.
