Abstract
Cancer vaccines are emerging as an attractive modality for tumor immunotherapy. However, their practical application is seriously impeded by the complex fabrication and unsatisfactory outcomes. Herein, we construct bacterial outer membrane vesicles (OMVs)-based in situ cancer vaccine with phytochemical features for photodynamic effects-promoted immunotherapy. By simply fusing thylakoid membranes with OMVs, bacteria-plant hybrid vesicles (BPNs) are prepared. After systemic administration, BPNs can target tumor tissues and stimulate the activation of immune cells, including dendritic cells (DCs). The photodynamic effects derived from thylakoid lead to the disruption of local tumors and then the release of tumor-associated antigens that are effectively presented by DCs, inducing remarkable tumor-specific CD8+T cell responses. Moreover, BPNs can efficiently ameliorate the immunosuppressive tumor microenvironment and further boost immune responses. Therefore, both tumor development and metastasis can be efficiently prevented. This work provides a novel idea for developing a versatile membrane-based hybrid system for highly efficient tumor treatment.

Swathi Krishna S, Thennavan A, Kanthlal SK. Dietary foods containing nitric oxide donors can be early curators of SARS-CoV-2 infection: A possible role in the immune system. J Food Biochem 2021; 46:e13884. [PMID: 34374096 PMCID: PMC8420599 DOI: 10.1111/jfbc.13884] [Citation(s) in RCA: 5] [Impact Index Per Article: 1.7] [Reference Citation Analysis] [Abstract] [Key Words] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/25/2021] [Revised: 07/09/2021] [Accepted: 07/15/2021] [Indexed: 12/13/2022]
Abstract
Severe acute respiratory syndrome coronavirus 2 (SARS CoV-2) is a lethal virus that causes COVID-19 (Coronavirus disease 2019), the respiratory illness that has caused the COVID-19 pandemic. Even though multiple pharmacological trials are ongoing, there is no proof that any treatment will effectively cure or prevent COVID-19. Currently, COVID-19-infected patients are being managed with non-specific medications to suppress the symptoms and other associated co-morbidities. Nitric oxide is a bio-signaling molecule that has been shown to be effective for treating several viral infections in humans. Household Natural foods rich in nitrites and nitrates (NO donors) have been scientifically proven to have therapeutic benefits against immune-related respiratory tract infections. It was understood that NO could inhibit the early stage of SARS CoV-2 invasion into the human cell. Fruits and vegetables containing nitrites and nitrates have been revised and are now thought to be potential anti-CoV agents for effective control of other associated systemic disorders. The purpose of this review is to highlight some key facts about the treatment and prevention of COVID-19 infection with foods rich in nitric oxide and its donors. PRACTICAL APPLICATIONS: Improving the body's immune system is the early step to be considered as a preventive measure to stop the spreading of COVID-19 infection. Emerging research continues to mount that dietary nitrates/nitrites from plant foods are being healthy as well as keep us away from infectious diseases. They are now incorporated into low-risk adjuvant therapy for various infections and systemic disorders. This concept portrays the regular consuming foods such as fruits and vegetables that are rich in nitric oxide which have the potential to promote health, improve general well-being, and reduce the risk associated with the highly contagious diseases. Hence, we recommend adding nitrates and nitrites-containing food to the regular diet to improve the self-immunity as well as to fight against COVID-19 disease.

Abstract
Besides their function as a physical barrier against pathogens, β-defensins possess the ability to induce direct or indirect chemotaxis in leukocytes of mammals. However little is known about the ability of defensins to guide the migration of macrophages in fish. The objective of our study was to investigate whether β-defensin 1 (maBD1) can recruit leukocytes (specifically macrophages) in vivo and in vitro in a farmed cyprinid fish Megalobrama amblycephala. The M. amblycephala β-defensin 1 (maBD1) gene was amplified from the head-kidney transcriptome. Synthetic maBD1 polypeptide (as well as its N-terminus half, but not the C-terminus half) was capable of inducing the migration of leukocytes (specifically macrophages) at concentrations from 26.0 μg/mL to 52.0 μg/mL in head kidney tissue in vitro. When injected intraperitoneally in vivo, the number of leukocytes in the peritoneal cavity was in positive correlation with the maBD1 concentration. maBD1 also induced the expression of two proinflammatory cytokines (IL-1beta and TNF-alpha) in spleen, head and body kidney, and hepatopancreas. These results strongly indicate that BD1 has a chemoattractant capacity for macrophages, as well as the ability to modulate the expression of proinflammatory cytokines in fish.

JOURNAL OF THE SCIENCE OF FOOD AND AGRICULTURE 2017; 97:4727-4736.

Abstract
BACKGROUND Coriandrum sativum L. seed is generally used as a spice and crude drug. Although many functions of the various components in C. sativum L. seed have been reported, the immunostimulatory effect of water-soluble components in C. sativum L. seed has not been studied. In the present study, we focused on the immunostimulatory effect of C. sativum L. seed aqueous extract (CAE) on macrophages as a novel health function of C. sativum L. seed components. RESULTS CAE significantly enhanced the production of tumor necrosis factor (TNF)-α and interleukin (IL)-6 in both RAW264.7 cells and peritoneal macrophages by enhancing the expression levels of these cytokine genes. CAE also stimulated nitric oxide (NO) production and the phagocytosis activity in RAW264.7 cells. We suggest that the activity of CAE is a result of the upregulation of mitogen-activated protein kinase and nuclear factor-κB cascades via TLR4. In addition, IL-6 production by peritoneal macrophages collected from CAE-administered mice was significantly enhanced, suggesting that CAE could stimulate macrophage activity in vivo. CONCLUSION The findings of the present study suggest that CAE contains a novel water-soluble component with an immunostimulatory effect on macrophages. CAE would contribute to activating host defense against pathogens by stimulating the innate immunity. © 2017 Society of Chemical Industry.

Exp Parasitol 2017; 178:37-44. [PMID: 28527905 DOI: 10.1016/j.exppara.2017.05.002] [Citation(s) in RCA: 10] [Impact Index Per Article: 1.4] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/25/2016] [Revised: 04/25/2017] [Accepted: 05/16/2017] [Indexed: 11/24/2022]
Abstract
BACKGROUND Neospora caninum is an apicomplexan parasite closely related Toxoplasma gondii, which causes neurological disease and abortion in multiple animal species. Macrophage polarization plays an important role in host immune responses to parasites infection, such as Toxoplasma gondii, Leishmania, Trypanosoma cruzi. However, the dynamics of macrophage polarization, as well as the possible mechanism that regulate macrophage polarization, during N. caninum infection remains unclear. METHODS The M1 and M2-phenotypic markers of peritoneal macrophages from mice infected with tachyzoites of Nc-1 were analyzed by flow cytometry (FCM) analysis. Then J774A.1 cells were respectively treated with GW9662 and RGZ, and stimulated by tachyzoites of Nc-1. M1 and M2-phenotypic markers were determined by FCM and ELISA. And the activations of PPAR-γ and NF-κB were determined by Western blotting. RESULTS In this study, our data showed that macrophages were preferentially differentiated into the M1 type during the acute stage of N. caninum infection, while the level of M2 macrophages significantly increased during the chronic stage of infection. In vitro study, compared with the GW9662 group and RGZ group, N. caninum can promote M2-polarized phenotype through up-regulate the activity of PPAR-γ and inhibting NF-κB activation. CONCLUSION In conclusion, this study demonstrated that macrophages are plastic since M1 differentiated macrophages can express M2 markers with N. caninum infection through up-regulating the activity of PPAR-γ and inhibting NF-κB activation and may be providing new insights for the prevention and treatment of N. caninum infection.

Immunostimulatory effect of dried bonito extract on mouse macrophage cell lines and mouse primary peritoneal macrophages. Cytotechnology 2017; 69:229-244. [PMID: 28084562 DOI: 10.1007/s10616-016-0053-4] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/21/2016] [Accepted: 12/07/2016] [Indexed: 10/20/2022] Open
Abstract
Dried bonito is a preserved food used in Japan, which contains abundant flavor ingredients and functional substances. We focused on the immunostimulatory effect of dried bonito extract (DBE) on mouse macrophage-like J774.1 cells, RAW264.7 cells, and mouse primary peritoneal macrophages. DBE significantly stimulated the production of tumor necrosis factor-α (TNF-α) and interleukin-6 (IL-6) by both J774.1 cells and peritoneal macrophages by enhancing the cytokine gene expression levels. In addition, DBE stimulated nitric oxide production by enhancing the expression of inducible nitric oxide synthase in RAW264.7 cells. DBE also increased the phagocytosis activity of J774.1 cells. Immunoblot analysis revealed that DBE has an immunostimulatory effect on macrophages through activation of mitogen-activated protein kinase and nuclear factor-κB cascades. TNF-α production enhanced by DBE was partially inhibited by treatment with TLR4 inhibitor TAK-242, whereas IL-6 production enhanced by DBE was almost inhibited. These results suggested that DBE is thought to strongly stimulate the TLR4 signaling pathway for macrophage activation, and its activation is also involved in other signaling. Finally, the phagocytosis activity of peritoneal macrophages from DBE-administered BALB/c mice increased significantly, suggesting that DBE has the potential to stimulate macrophage activity in vivo. In conclusion, these data indicated that DBE contributes to activating host defense against pathogens by activating innate immunity.
