Abstract
The blood coagulation test is an indispensable test for monitoring the blood coagulation and fibrinolysis functions. Currently, activated partial thromboplastin time (APTT) is the most widely used approach to coagulation testing. However, APTT reagents need to be optimized due to the fact that they are unstable, highly variable, and cannot be easily controlled. In this study, we created apoptotic cell-inspired methacryloyloxyethyl phosphorylserine (MPS) particles for blood coagulation as an alternative to conventional APTT reagents. Particle size could be controlled by changing the concentration of the polymer. The blood coagulation ability of particles was stable at different environmental temperatures. Moreover, the procoagulant activity could be enhanced by increasing the concentration to 0.06 mg/mL and reducing the size of the particles to around 900 nm. Fibrin clotted by particles showed no significant difference from that formed by APTT regent Actin FSL. We propose that MPS particles are a potential alternative to Actin FS for the application of blood coagulation tests.

Abstract
Phosphatidylserine (PtdSer), one of the phospholipids that the apoptotic cell exposes, has emerged for anti-inflammatory therapy via polarizing inflammatory microglia (Mi1) to anti-inflammatory phenotype (Mi2). In this study, we report microglia polarization effect of PtdSer-exposing polymeric particles (PSPs). PSPs upregulated Mi2 microglia and suppressed Mi1 microglia through peroxisome proliferator-activated receptor gamma upregulation in vitro and in vivo. This study highlights the potential of PSPs for anti-inflammatory therapy.

Abstract
Apoptotic cells are known to suppress microglial inflammation in the brain by presenting phosphatidylserine. In this study, we newly designed polymeric particles that expose the anti-inflammatory site of phosphatidylserine to serve as an apoptotic cell-mimetic anti-inflammatory platform. The prepared anti-inflammatory particles showed no cytotoxicity and significantly inhibited the production of the inflammatory cytokine interleukin-6 against lipopolysaccharide stimulation in the microglia cell line MG6. This novel polymeric particle has potential for establishing a "cell-free" apoptotic cell-mimetic treatment for intracerebral inflammation.

Abstract
The field of biomaterials has seen a strong rejuvenation due to the new potential to modulate immune system in our body. This special class of materials is called "immunomodulatory biomaterials". Generally, three fundamental strategies are followed in the design of immunomodulatory biomaterials: (1) immuno-inert biomaterials, (2) immuno-activating biomaterials, and (3) immuno-tolerant biomaterials. While many applications of immuno-inert biomaterials such as biocompatible medical implants have been already proposed in the past decades, the ability to engineer biological activity into synthetic materials greatly increases the number of their potential uses and improves their performance in more traditional applications. The major focus of researchers is now set on developing immuno-tolerant biomaterials for anti-inflammatory therapies. In this review, we therefore introduce recent developments of immuno-tolerant biomaterials. Especially we introduce an apoptotic cell membrane-inspired polymer and its post-inflammatory effects on immune cells in this article.
