          IL-6和TNF-α水平,以及细胞内Ca 浓度均显著升高(P<0.01)。在超剂量红花提取物致敏血清诱导下,与佐剂处理组比较,红花

          Study on the immunotoxicity and mechanism of Carthamus tinctorius extract on RBL-2H3 cells

          pharmacology and Toxicology of Traditional Chinese Medicine, Chongqing Academy of Chinese Materia Medica/

          Chinese Medicine, Chongqing 400065, China)

          ABSTRACT   OBJECTIVE  To  investigate  the  immunotoxicity  and  potential  mechanism  of  Carthamus  tinctorius  extract  on  RBL-
          2H3  cells  via  direct  induction  and  induction  by  sensitized  serum  prepared  with  an  overdose  of  the  extract.  METHODS  For  direct
          induction  by  C.  tinctorius  extract,  RBL-2H3  cells  were  divided  into  normal  control  group (no  treatment)  and  C.  tinctorius  extract
          group (10  mg/mL).  For  induction  by  sensitized  serum  prepared  with  an  overdose  of  C.  tinctorius  extract,  rats  were  divided  into
          normal  control  group (no  treatment),  adjuvant-treated  group (1  mL  adjuvant),  C.  tinctorius  extract-induced  sensitization  group
         (2.04  g/mL),  and  ovalbumin (OVA)-induced  sensitization  group (50  mg/mL).  Sensitization  was  performed  once  every  other  day
          for  a  total  of  3  times.  Morphological  changes  of  RBL-2H3  cells  were  observed,  the  degranulated  rate  of  cells  was  counted,  and
          histamine content was determined; the release rate of β-hexosaminidase (β-Hex) was calculated, the levels of interleukin-6 (IL-6)
          and  tumor  necrosis  factor-α (TNF-α)  and  intracellular  Ca²⁺  concentration  were  detected.  RESULTS  Under  direct  induction  by  C.
          tinctorius extract, compared with the normal control group, the volume of cells in the C. tinctorius extract group was significantly
          reduced and cell density decreased; the degranulation rate of cells, histamine content, β-Hex release rate, IL-6 and TNF-α levels,
          as well as intracellular Ca²⁺ concentration were all significantly increased (P<0.01). Under induction by sensitized serum prepared
          with an overdose of C. tinctorius extract, compared with the adjuvant-treated group, the above indicators in the C. tinctorius extract-
          induced  sensitization  group  and  the  OVA-induced  sensitization  group  showed  consistent  changes  with  those  in  the  C.  tinctorius
          extract  group  under  direct  induction,  all  being  significantly  elevated (P<0.01).  CONCLUSIONS  C.  tinctorius  extract  may  affect
          degranulation  of  RBL-2H3  cells  and  promote  Ca²⁺  influx  accompanied  by  the  release  of  pro-inflammatory  cytokines  through  two
          approaches:  direct  induction  and  induction  by  sensitized  serum  prepared  under  overdose  administration.  Its  mechanism  may  be
          related  to  the  activation  of  the  calcium  signaling  pathway  and  the  regulation  of  inflammatory  pathways  under  the  synergistic  effect
          of multiple components.
