T細胞介導的細胞免疫在控制腫瘤生長方面發揮著重要作用， t細胞在發揮抗瘤效應（分泌細胞因子和直接殺傷）之前必須先經過活化，體內專職抗原提呈細胞（ apc ）細胞並使其活化，樹突狀細胞（ dendriticcell ， dc ）為t細胞的激活提供雙重信號， t細胞藉助tcr識別由dcmhc分子遞交的抗原肽后，通過tcr - cd3復合體傳遞抗原特異性識別信號（第一信號） ，以cd28為主的t細胞表面輔佐分子識別dc表面b7分子，傳遞非特異性協同刺激信號（第二信號） ，在機體抗腫瘤免疫應答中處于核心地位。Mdamb543 human mammary carcinoma cells were used for the photodynamic effect experiment in vitro, they were incubated with varying concentrations of photosensitizers dissolved in rpmi 1640 medium, then were irradiated by copper vapor laser with mixed wavelength light of 510. 6nm and 578. 2nm. cell survival rate was analyzed by mtt assay

但是，學者們發現這一療法存在著如下的缺陷：單一ctl表位抗原肽的應用其抗腫瘤作用弱於多種腫瘤抗原的聯合應用，且有誘導免疫耐受的潛在危險，有時反而會促進腫瘤的生長；事先需對患者的hla單倍型進行鑒定，以確定ctl表位與hla單倍型是否匹配，目前尚缺乏能與所有hla單倍型相匹配的ctl表位，從而限制了這一療法的應用；這一療法所產生的ctl在體外能有效殺傷經腫瘤抗原肽共孵育過的靶細胞，但對腫瘤細胞的殺傷能力較弱：這種l表位抗原肽缺乏cd4汀h細胞相關的表位，因此，不能誘導有效的th細胞免疫應答。The anti - hepatic cancer immunity of whole cell lysates pulsed dendritic cell
