Abstract
Description
도 2. 본 발명의 실리카 입자 조성물 및 ch-OSA®(콜린-안정화 오르토규산, BioSil™)에 의한 T 세포 활성화.
도 3. Kerek 대비 본 발명의 실리카 입자 조성물에 의한 CD4+ 및 CD8+ 발현.
도 4. Kerek(+ 양성 대조군, SEB) 대비 본 발명의 실리카 입자 조성물에 의한 CD4+ 및 CD8+ 발현.
도 5. Biosil™ 대비 본 발명의 실리카 입자 조성물에 의한 CD4+ 및 CD8+ 발현.
도 6. Biosil™(+ 양성 대조군, SEB) 대비 본 발명의 실리카 입자 조성물에 의한 CD4+ 및 CD8+ 발현.
도 7. 23-40 mM Si ± 염화나트륨의 최종 농도로 알칼라인 규산나트륨 용액의 pH 중화(pH 7) 및 ~20 h의 인큐베이션(분산액의 경우 > 3 nm)에 의해 또는 500 mM 알칼라인 규산염 용액을 pH 0.8-1로 조정하고 세포 배양액에의 첨가 전에 ~20 h의 인큐베이션(<3 nm 분산액)(n = >8)에 의해 제조된, 다양한 크기의 초미세 나노실리카에 의한 CD4 및 CD8 T 세포의 활성화. 입자 평균 직경(DV0.5)이 보고된다.
도 8. 'HS-7'로 명명되고 23 mM Si의 최종 농도로 알칼라인 규산나트륨 용액의 pH 중화(pH 7)에 의해 제조되고 세포 배양액(n = 6-7)에의 첨가 전에 ~20 h 인큐베이션된 초미세 나노실리카에 의한 다양한 Th 계통 세포 유형의 활성화. 입자는 반복 분석으로부터 평균 직경(DV0.5) = 3.4-3.8 nm을 갖는다.
도 9. HUVEC 세포의 융합성에 대한 suc. uSANS (a), 인 시튜 uSANS (b) 및 이들의 비히클 대조군 (c)의 영향. 세포 독성(즉, 세포 모양의 변화 및/또는 세포사)을 유발하였기 때문에, HS7으로 명명된, 연구된 세 번째 나노실리카에 대해서는 참고 데이터를 나타낼 수 없었고, 모든 3개 농도(1, 2 및 4 mM Si)에서 단기간의 인큐베이션 후(< 1 h) 및 4-5 h 인큐베이션 후 대부분의 세포는 4 mM 농도에서 사멸하였다. 더 낮은 농도의 HS7(0.1, 0.25 및 0.5 mM Si)을 이용한 하기 실험에서는, 0.5 mM Si에서조차 독성이 나타났다.
도 10. 시간의 경과에 따라 측정된 pZap70은 T 세포 수용체와 상호작용하는 나노실리카로부터 비롯된 T 세포의 신속한 활성화를 입증하고, 이는 ZAP-70의 인산화를 초래한다.
도 11. 몰리브덴산염 분석에 의해 결정된 바와 같은 산성 저장 중의 uSANS의 화학적 불안정성. 모든 재료를 실온 또는 4℃에 저장하였다. 수크로스-안정화 uSANS(Suc uSANS)는 pH 2.15±0.15 또는 1.5±0.1에서 저장한 반면, 비-안정화 재료(NS uSANS)는 pH 1.5±0.1에서 저장하였다. 더 높은 OD는 더 큰 화학적 불안정성(즉, 덜 응축된 규산염)을 나타낸다.
도 12. 중화 (pH 7) 시 시간의 경과에 따른 uSANS의 화학적 불안정성. 몰리브덴산염 분석을 사용하여 중화 전(pH 2.3) 및 후(t 0h 내지 t 6h)에 uSANS와 가용성 규산염(Si(OH)4)의 불안정성을 비교하였다.
도 13. 다양한 인큐베이션 기간(1분 내지 1h) 후 인 시튜 형성된 uSANS(40 mM Si)의 화학적 불안정성.
