Abstract
We designed, synthesized, and characterized a Raman nanoprobe made of dye-sensitized single-walled carbon nanotubes (SWCNTs) that can selectively target biomarkers of breast cancer cells. The nanoprobe is composed of Raman-active dyes encapsulated inside a SWCNT, whose surface is covalently grafted with poly(ethylene glycol) (PEG) at a density of ∼0.7% per carbon. Using α-sexithiophene- and β-carotene-derived nanoprobes covalently bound to an antibody, either anti-E-cadherin (E-cad) or anti-keratin-19 (KRT19), we prepared two distinct nanoprobes that specifically recognize biomarkers on breast cancer cells. Immunogold experiments and transmission electron microscopy (TEM) images are first used to guide the synthesis protocol for higher PEG-antibody attachment and biomolecule loading capacity. The duplex of nanoprobes was then applied to target E-cad and KRT19 biomarkers in T47D and MDA-MB-231 breast cancer cell lines. Hyperspectral imaging of specific Raman bands allows for simultaneous detection of this nanoprobe duplex on target cells without the need for additional filters or subsequent incubation steps. Our results confirm the high reproducibility of the nanoprobe design for duplex detection and highlight the potential of Raman imaging for advanced biomedical applications in oncology.

Abstract
Understanding the effects mediated by a set of nanoparticle (NP)-bound host biomolecules, often indicated with the umbrella term of NP corona, is essential in nanomedicine, nanopharmacology, and nanotoxicology. Among the NP-adsorbed proteome, some factors mediate cell binding, endocytosis, and clearing by macrophages and other phagocytes (opsonins), while some others display few affinities for the cell surface (dysopsonins). The functional mapping of opsonins and dysopsonins is instrumental to design long-circulating and nanotoxicologically safe next-generation nanotheranostics. In this review, we critically analyze functional data identifying specific proteins with opsonin or dysopsonin properties. Special attention is dedicated to the following: (1) the simplicity or complexity of the NP proteome and its modulation, (2) the role of specific host proteins in mediating the stealth properties of uncoated or polymer-coated NPs, and (3) the ability of the innate immune system, and, in particular, of the complement proteins, to mediate NP clearance by phagocytes. Emerging species-specific peculiarities, differentiating humans from preclinical animal models (the murine especially), are highlighted throughout this overview. The operative definition of opsonin and dysopsonin and the measurement schemes to assess their in vitro efficacy is critically re-examined. This provides a shared and unbiased approach useful for NP opsonin and dysopsonin systematic identification.

Mechanistic Understanding of Cell Recognition and Immune Reaction via CR1/CR3 by HAP- and SiO 2-NPs. BIOMED RESEARCH INTERNATIONAL 2020; 2020:7474807.

Abstract
Nanodrug carrier will eventually enter the blood when intravenously injected or in other ways. Meanwhile, a series of toxic effects were caused to the body with the formation of nanoparticle protein corona. In our studies, we try to reveal the recognition mechanism of nanoparticle protein corona by monocyte and the damage effect on immune cells by activated complement of hydroxyapatite nanoparticles (HAP-NPs) and silicon dioxide nanoparticles (SiO2-NPs). So expressions of TLR4/CR1/CR were analyzed by flow cytometry (FCM) in order to illuminate the recognition mechanism of nanoparticle protein corona by monocyte. And the expression of ROS, cytokines, adhesion molecules, and arachidonic acid was measured when THP-1 and HUVECs were stimulated by NP-activated complement. The results showed that HAP-NPs can be recognized by the opsonin receptor (iC3b/CR3) model, while plasma protein, opsonin receptor, and Toll-like receptors are all likely launch cell recognition of SiO2-NPs. And it was considerate that NP-activated complement can damage THP-1 and HUVECs, including oxidative stress, inflammation, and increased vascular permeability. So the surface of nanodrug carrier can be modified to avoid being clear and reduce the efficacy according to the three receptors (TLR4/CR1/CR3).

Ding T, Sun J. Formation of Protein Corona on Nanoparticle Affects Different Complement Activation Pathways Mediated by C1q. Pharm Res 2019; 37:10. [PMID: 31872347 DOI: 10.1007/s11095-019-2747-8] [Citation(s) in RCA: 10] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/31/2019] [Accepted: 12/05/2019] [Indexed: 12/26/2022]
Abstract
PURPOSE As nanoparticles (NPs) are intravenously entering the bloodstream, proteins in the plasma can recognize and bind them to form a protein corona that affects how NPs are perceived by biological systems. The complement is an essential part of the innate immunity that contributes to non-specific host defense. How complement recognizes NPs has not been elucidated. Here, we developed a proteomics and biochemical approach to understand the applied risk of activated complement by NPs. METHODS Complement proteins absorbed on Hydroxyapatite Nanoparticles (HAP-NPs) and Silicon dioxide Nanoparticles (SiO2-NPs) were analyzed by proteomics with LC-MS. The effect of complement activation was studied by iC3b/Sc5b-9/C3a/C4a/C5a with ELISA. An inhibitory model was established via EDTA and EGTA to confirm the selective pathway activation of both NPs. Finally, the regulation of complement by NPs was analyzed by western blot. RESULTS The results indicate that HAP-NPs start the activation of the complement through the classical pathway because of the absorption of C1q and the release of C1r/C1s. Meanwhile, the soluble regulatory molecules such as CFI, C4bp, and CFH tried to resist the complement system activation by the cleavage of C3 convertase. In contrast, SiO2-NPs can activate the alternative pathway of the complement through the absorption of CFD and CFB. CONCLUSION It was clarified that HAP-NPs and SiO2-NPs activate complement through different mechanisms. These studies provide a scientific basis for the design and modification of nano-drug carriers for delaying their recognition and clearance by the mononuclear phagocytic system and simultaneously reducing the immunotoxicity of NPs. The understanding of protein corona is conducive to innovation in the field of "immune-safe-by-design" nanomedicines.

Abstract
Nanodiamonds are promising nanomedicines for diagnostic and therapeutic applications. As nanodiamonds are mainly administered intravenously, it is critical to understand the humoral immune response upon exposure to nanodiamonds. Here, we report the interactions of pristine, oxidized, and PEG-functionalized nanodiamonds with human complement, an important part of our humoral innate immunity. In particular, we report the nanodiamond binding properties of the recognition protein of the classical complement pathway: C1q, which also takes part in many other physiological and pathological processes. Our results show similar trends in the effects of C1q on the three types of nanodiamonds. Complement activation assays using human serum show that the nanodiamonds trigger slight activities via the alternative pathway and no response via the classical pathway. Nevertheless, surface plasmon resonance shows that C1q binds the nanodiamonds and transmission electron microscopy reveals their agglutination. Studies with macrophages further show that C1q attachment affects their phagocytosis and cytokine response.
