Abstract
Many studies in the bone tissue engineering field have focused on the interactions between materials and bone marrow stem cells. With the development of osteoimmunology, the immune cells' essential role in biomaterial-mediated osteogenesis has increasingly been recognized. As a promising therapeutic candidate for bone defects due to their prominent biocompatibility, tuneability, and versatility, it is necessary to develop alginate-based biomaterials that can regulate immune cells, especially macrophages. Moreover, modified alginate-based biomaterials may facilitate better regulation of macrophage phenotypes by the newly endowed physicochemical properties, including stiffness, porosity, hydrophilicity, and electrical properties. This review summarizes the role of macrophages in bone regeneration and the recent research progress related to the effects of alginate-based biomaterials on macrophages applied in bone tissue engineering. This review also emphasizes the strategies adopted by material design to regulate macrophage phenotypes, the corresponding macrophage responses, and their contribution to osteogenesis.

J Biomed Mater Res A 2022; 111:1006-1020.

Abstract
Previous research has found that octacalcium phosphate (OCP) increases macrophage accumulation and alters the initial inflammatory response. However, the role of the immune response induced by OCP in osteogenesis remains unknown. This study investigated the behavior of macrophages and bone regeneration capacity during the early inflammatory stage of OCP-mediated osteogenesis. To assess the change in macrophage polarization and osteogenic capacity, we used a standardized rat defect model filled with OCP or calcium-deficient hydroxyapatite (CDHA)-a material obtained through the hydrolysis of the original OCP. OCP or CDHA granules were incubated with RAW264 cells for 5 days to investigate the effect of physicochemical characteristics on macrophage cytokine/chemokine expression in vitro. Our in vivo results show that due to the OCP implantation, macrophages in the rat tibial defect area tend to polarize to the M2 phenotype (anti-inflammatory) and inhibit the formation of the M1 phenotype (pro-inflammatory). In comparison to CDHA, OCP exhibited superior bone regeneration potential due to its rapid promotion of cortical bone healing and stimulation of macrophage-related growth factors. Furthermore, our in vitro results have shown that OCP regulates the expression of macrophage chemokines over time. Compared to incubation with CDHA, incubation with OCP caused changes in the ionic microenvironment. These findings suggest that the OCP-mediated macrophage polarization and secretion profile not only regulate immune function but also positively affect osteogenesis.

Abstract
Osteoporosis is a kind of global chronic bone disease characterized by progressive loss of bone mass and bone quality reduction, leading to a largely increased risk of bone fragility. In clinics, the current treatment of osteoporosis relies on the inhibition of bone damage by osteoclasts but ignores the function of immune cells in the progress of osteoporosis, leading to much compromised therapeutic efficacy. In this work, a highly effective osteoporosis-immunotherapeutic modality is established for the treatment of osteoporosis based on acid neutralization in synergy with immune microenvironment regulation by a specially designed nanocatalytic medicine, calcein functionalized calcium-aluminum-layered double hydroxide (CALC) nanosheets. Briefly, the mildly alkaline CALC nanosheets could neutralize the acidic microenvironment of osteoporosis accompanying the acidity-responsive LDH degradation. Subsequently, calcium phosphate nanoparticles (CAPs) are generated by the reaction between the released Ca2+ from LDH degradation and endogenous phosphates, resulting in M2 phenotype anti-inflammatory differentiation of bone macrophages through a c-Maf transcriptional factor pathway and the following activity enhancements of regulatory T cells (Treg) and the deactivation of T helper 17 cells (TH17). Both in vitro and in vivo results show an excellent therapeutic efficacy on osteoporosis featuring a significant BV/TV (%) enhancement of femurs from 6.2 to 10.7, demonstrating high feasibility of this therapeutic concept through the combined acid neutralization and immune regulation. Such an inorganic nanomaterial-based strategy provides a novel, efficient, and biosafe therapeutic modality for intractable osteoporosis treatment, which will benefit patients suffering from osteoporosis.

Abstract
Two-dimensional (2D) materials have emerged as an important class of nanomaterials for technological innovation due to their remarkable physicochemical properties, including sheet-like morphology and minimal thickness, high surface area, tuneable chemical composition, and surface functionalization. These materials are being proposed for new applications in energy, health, and the environment; these are all strategic society sectors toward sustainable development. Specifically, 2D materials for nano-imaging have shown exciting opportunities in in vitro and in vivo models, providing novel molecular imaging techniques such as computed tomography, magnetic resonance imaging, fluorescence and luminescence optical imaging and others. Therefore, given the growing interest in 2D materials, it is mandatory to evaluate their impact on the immune system in a broader sense, because it is responsible for detecting and eliminating foreign agents in living organisms. This mini-review presents an overview on the frontier of research involving 2D materials applications, nano-imaging and their immunosafety aspects. Finally, we highlight the importance of nanoinformatics approaches and computational modeling for a deeper understanding of the links between nanomaterial physicochemical properties and biological responses (immunotoxicity/biocompatibility) towards enabling immunosafety-by-design 2D materials.
