홍삼유래 ginsenosides Rh1의 단핵구 U937 세포 유착조절 효과

초록

Cell-cell adhesion managed by various adhesion molecules is known to be one of pathophysiological phenomena found in numerous immunological diseases such as rheumatoid arthritis and allergic diseases. In this study, we examined the regulatory role of ginsenosides (G)- Rh1, reported to display anti-inflammatory and anti-allergic effects, on CD29-mediated cell adhesion. G-Rh1 significantly suppressed U937 cell-cell adhesion mediated by CD29 but not CD43. It also blocked U937 cell-fibronectin adhesion, mediated by activated CD29, up to 30%. In agreement, this compound also significantly decreased the surface level of CD29 but not CD43 as well as other costimulatory molecules such as CD69, CD80, and CD86. Therefore, these results suggest that G-Rh1 may have inhibitory function on CD29-mediated cell adhesion events, probably contributing to its anti-inflammatory and anti-allergic activities.
