(2) Active targeting
Nanoparticle passive targeting can be enhanced by ‘active targeting’, where specific ligands (peptides, antibodies, aptamers, or small molecules) are attached to the nanoparticle surface to bind receptors/antigens overexpressed on cancer cells. Targeting increases accumulation in tumors and lessens exposure to healthy tissue, which can improve a toxic drug’'s therape
심근의 경우 ATP 수요에 맞춰 호기성 호흡에 의한 ATP 합성을 최대 8~10배까지 올릴 수 있다. 이는 매우 즉각적이어서 시시각각으로 변하는 ATP의 수요를 맞춰줄 수 있을 정도이다. 즉, 짧은 시간 동안에도 ATP 분해로 인한 세포질내 ADP 증가가 ATP 합성에 의한 미토콘드리아 matrix내 ADP 감소와 정확히 일치하는
of IgE which has blocking capacity inhibiting binding between allergen and IgE on mast cells and basophils.
Immune response to allergen
Immune response influenced by several factors
Genetic susceptibility
The nature of antigen which initiates the disease
Challenge with infections and bacteria
With complex stimulation, naive T-cells are activated by APC and differentiate into Th1, Th2, Th17, Th19
*’Nano’ means….
Nanometer: one billionth of a meter
Nano-: prefix comes from the Greek word for ‘dwarf’
Chemical, physical, and biological properties that differ from those of their larger, or bulk counterparts
Nanotechnology: The National Nanotechnology Initiative(NNI)-> the science of materials and phenomena in the range of 1 to 100nm in diameter
*Features of ‘nanoparticles
Actin polymerization
ATP bound actin polymerizes to form polar microfilament
Cell morphology, motility
Tightly regulated, coordinated by different actin-binding
proteins
3. Intracellular transport
- Microfilament is concerned with intracellular
transport of vesicles or other organelles
- Mitochondria transport in cells
Phalloidin method used in many actin dete
