Effects of oxidized high-density lipoprotein on membrane fluidity and the expression of lymphocyte function associated antigen-1 of monocyte / 中国病理生理杂志

ABSTRACT

AIM: To investigate the effects of oxidized high-density lipoprotein (oxHDL) on membrane fluidity and the expression of lymphocyte function associated antigen(LFA-1) of monocyte. METHODS: The membrane fluidity of THP-1 cells was assayed by fluorescence anisotropy with DPH (1,6-dipheny-1,3,5-hexatriene), a fluorescent probe; The LFA-1 expression on THP-1 cells were assayed by flow cytometry with indirect immunofluorescence.RESULTS: The membrane fluidity of THP-1 cells was reduced by 45% and 52% respectively ( P
