Abstract
INTRODUCTION The current study investigated the antioxidant and anti-inflammatory effects of ethanol extracts from Lindera glauca twig (LGT) and leaf/stem (LGLS). METHODS The antioxidant activities were measured by total content of polyphenol and flavonoid, DPPH radical scavenging, and ABTS+ radical scavenging activity. To evaluate the anti-inflammatory effect in the LPS-induced RAW 264.7 cells, protein and mRNA expression of major inflammatory factors were analyzed using Western blot analysis and RT-PCR. RESULTS The total polyphenol content of LGT and LGLS was 88.45 ± 11.74 and 115.75 ± 7.87 GA mg/g, respectively. The total flavonoid content was 66 ± 2.89 and 74.33 ± 2.89 QE mg/g. Both LGT and LGLS showed high DPPH and ABTS+ radical scavenging activities. Neither LGT nor LGLS was cytotoxic to RAW 264.7 cells. The anti-inflammatory activities were measured by LPS-induced RAW 264.7 cells. LGT and LGLS showed inhibition of the LPS-induced production of nitric oxide (NO), inducible NO synthase, cyclooxygenase-2 at the protein and mRNA levels, as determined by Western blotting and RT-PCR, respectively. In addition, the release of tumor necrosis factor-α and interleukin-6 mRNA expression levels of these cytokines was reduced by LGT and LGLS. CONCLUSION These results suggest that LGT and LGLS extracts have potential for use as a functional antioxidant and anti-inflammatory ingredient in cosmetic industry.

Abstract
Today, adoptive cell therapy has many successes in cancer therapy, and this subject is brilliant in using chimeric antigen receptor T cells. The CAR T cell therapy, with its FDA-approved drugs, could treat several types of hematological malignancies and thus be very attractive for treating solid cancer. Unfortunately, the CAR T cell cannot be very functional in solid cancers due to its unique features. This treatment method has several harmful adverse effects that limit their applications, so novel treatments must use new cells like NK cells, NKT cells, and macrophage cells. Among these cells, the CAR macrophage cells, due to their brilliant innate features, are more attractive for solid tumor therapy and seem to be a better candidate for the prior treatment methods. The CAR macrophage cells have vital roles in the tumor microenvironment and, with their direct effect, can eliminate tumor cells efficiently. In addition, the CAR macrophage cells, due to being a part of the innate immune system, attended the tumor sites. With the high infiltration, their therapy modulations are more effective. This review investigates the last achievements in CAR-macrophage cells and the future of this immunotherapy treatment method.

Abstract
BACKGROUND Despite the dysregulation and function of G-quadruplex-forming sequence containing lncRNA (GSEC) have been widely reported in human cancers, there are few available data revealing its role in sepsis. OBJECTIVE To assess the expression and function of GSEC in the development of sepsis and its potential molecular mechanism. MATERIALS AND METHODS A total of 78 sepsis patients, 55 non-sepsis intensive care unit patients, and 42 healthy individuals were enrolled in this study. The expression of GSEC was evaluated in plasma and macrophage cells with polymerase chain reaction. The inflammation response of sepsis patients and macrophage cells was analyzed with an enzyme-linked immunosorbent assay. The diagnostic and prognostic value of GSEC in sepsis patients were estimated by receiver operator curve (ROC) and Cox analysis. The molecular mechanism underlying the function of GSEC was investigated in RAW264.7 cell with luciferase reporter assay and cell transfection. RESULTS Significant upregulation of GSEC was observed in sepsis patients' plasma, which could discriminate sepsis patients from healthy and non-sepsis individuals. Upregulation of GSEC was positively correlated with inflammation cytokine levels and adverse prognosis of sepsis patients. In vitro, GSEC was found to modulate the expression level of miR-873-3p, which mediated the regulatory effect of GSEC on the inflammation and proliferation of RAW264.7. CONCLUSION Upregulated GSEC could serve as a biomarker of sepsis pathogenesis and development. GSEC regulates the inflammation and proliferation of macrophage cells through modulating miR-873-3p.

Abstract
The deficiency of survival motor neuron (SMN) protein can result in the onset of spinal muscular atrophy (SMA), an autosomal recessive disorder characterized by a progressive loss of motor neurons and skeletal muscle atrophy. The mechanism underlying SMA pathology remains unclear. Here, we demonstrate that SMN protein regulates oxidative stress and inflammatory response in microglia. Antisense oligonucleotide, which increases SMN protein expression (SMN-ASO), attenuated SMA model mice phenotypes and suppressed the activation of microglia in the spinal cord. The expression of oxidative stress marker in microglia was decreased by SMN-ASO injection in SMA model mice. Increased reactive oxygen species production and subsequent antioxidative stress reaction was observed in SMN protein-depleted RAW264.7. Furthermore, nuclear factor kappa B (NFκB) and c-Jun amino terminal kinase (JNK) signaling, which mainly mediate the inflammatory response, are activated in SMN protein-depleted RAW264.7. Tumor necrosis factor-α (TNF-α) production is also increased in SMN protein-depleted RAW264.7. These findings suggest that SMN protein regulates oxidative stress and inflammatory response in microglia, supporting current claims that microglia can be an effective target for SMA therapy.

Abstract
BACKGROUND Ischemia is the partial or complete blockage of blood supply to tissues. Extracellular vesicles (EVs) are emerging as a therapeutic tool for ischemic diseases. Most EV-based ischemia therapies are based on various stem cells. Here, we propose an alternative cell source for the isolation of pro-angiogenic EVs. METHODS EVs were isolated from a mouse macrophage cell line (Raw 264.7). The characteristic features of the macrophage-derived EVs (MAC-EVs) were assessed using transmission electron microscopy, nanoparticle tracking analysis, and Western blotting (WB) analysis. WB and qRT-PCR were performed to identify the pro-angiogenic VEGF and Wnt3a proteins and microRNAs (miR-210, miR-126, and miR-130a) in the MAC-EVs. In vitro and in vivo Matrigel plug assays were performed to investigate the capacity of the MAC-EVs for tube (blood vessel-like) formation and new blood vessel formation and assessed by histology. RESULTS The MAC-EVs was positive for ALIX and negative for calnexin, with a round shape and an average size of 189 ± 65.1 nm. WB and qRT-PCR results revealed that VEGF, Wnt3a and miR-130a were more abundant in the MAC-EVs than cells. MAC-EVs treatment resulted in increased endothelial cellular proliferation, migration, and tube formation in vitro. In vivo assay results revealed that MAC-EVs increased the formation of new and larger blood vessels in the Matrigel plug of mice compared to the formation in the control group. CONCLUSION Our results suggest that MAC-EVs have the potential to induce angiogenesis in vitro and in vivo, could serve as a pro-angiogenic alternative for ischemic diseases.

Abstract
BACKGROUND Interleukin 33 is known to have an important influence in the process of myocardial infarction, and the immunoregulatory function of MSCs could be influenced by cell factors. In this study, we evaluated the therapeutic efficacy of IL-33-overexpressing bone marrow mesenchymal stem cells (IL33-MSCs) on myocardial infarction (MI) and detected the inflammatory level and cardiac function in rats. METHODS AND RESULTS First, we evaluated the proliferation of T cells and polarization of macrophages that had been co-cultured with Vector-MSCs or IL33-MSCs. Co-culture experiments indicated that IL33-MSCs reduced T cell proliferation and enhanced CD206+ macrophage polarization. Second, we determined the inflammation level and cardiac function of PBS-, Vector-MSC-, and IL33-MSC-injected rats. Echocardiography indicated that left ventricular ejection fraction (LVEF) was enhanced in IL33-MSC-injected rats compared with Vector-MSC-injected rats. Postmortem analysis of rat heart tissue showed reduced fibrosis and less inflammation in IL33-MSC-injected rats. CONCLUSION These studies indicated that the IL33-MSC injection improved heart function and reduces inflammation in rats with MI compared with PBS or Vector-MSC injections. IL-33 overexpression enhances the immunomodulatory function and therapeutic effects of MSCs on acute MI via enhancing the polarization of macrophages toward M2, enhancing the differentiation of CD4+ T cells toward CD4+IL4+Th2 cells, and finally, reducing heart inflammation and enhancing heart function.

Abstract
Calcium (Ca2+) is a pivotal intracellular second messenger and calmodulin (CaM) acts as a multifunctional Ca2+-binding protein that regulates downstream Ca2+ dependent signaling. Together they play an important role in regulating various cellular functions, including gene expression, maturation of phagolysosome, apoptosis, and immune response. Intracellular Ca2+ has been shown to play a critical role in Toll-like receptor-mediated immune response to microbial agonists in the HD11 chicken macrophage cell line. The role of that the Ca2+/CaM pathway plays in the intracellular survival of Salmonella in chicken macrophages has not been reported. In this study, kinome peptide array analysis indicated that the Ca2+/CaM pathway was significantly activated when chicken macrophage HD11 cells were infected with S. Enteritidis or S. Heidelberg. Further study demonstrated that treating cells with a pharmaceutical CaM inhibitor W-7, which disrupts the formation of Ca2+/CaM, significantly inhibited macrophages to produce nitric oxide and weaken the control of intracellular Salmonella replication. These results strongly indicate that CaM plays an important role in the innate immune response of chicken macrophages and that the Ca2+/CaM mediated signaling pathway is critically involved in the host cell response to Salmonella infection.
