    Abstract Polycystic ovary syndrome (PCOS) is an inflammatory endocrine-metabolic disorder related to reproductive system characterized by polycystic ovarian morphology, androgen excess, and chronic anovulation. Current treatments haven't been very successful in PCOS treatment and the problem still remains as a challenge. Therefore, new approaches should be applied to overcome the disease. Previous studies demonstrated immunomodulatory effects of R10 fraction of garlic in the treatment of inflammatory conditions such as cancer. Considering previous studies suggesting immunomodulatory therapy for PCOS, therapeutic effects of R10 fraction was evaluated in a mouse model of PCOS. To do so, PCOS was developed by intramuscular injection of estradiol valerate. Treatment with R10 fraction, isolated from garlic, was performed and the alterations in hormonal levels (estradiol, progesterone, and testosterone), T cell polarization markers (IFN-γ, IL-4, and IL-17), and expression of fertility-related genes (Gpx3 and Ptx3) were evaluated. The results showed that hormonal levels were elevated in PCOS model comparing to normal animals but were markedly modulated after treatment with R10 fraction. Moreover, a severe disturbance in T cell polarization with a significant reduction of fertility-related genes expression were detected in PCOS-induced ovaries. Treatment with R10 fraction also represented modulatory effects on T cell polarization by increasing IL-4 and decreasing IL-17 and IFN-γ levels. Accordingly, fertility-related genes were also modulated following treatment with R10 fraction in PCOS. Our study elucidated that R10 fraction of garlic possess immunomodulatory effects alleviating PCOS symptoms. This approach could be adjusted to give rise the optimum therapeutic results and considered as a candidate therapeutic approach for PCOS.

    Abstract It is believed that preformed antibodies are responsible for blood transfusion reactions and transplant rejections. In order to remove a tumor, the tissue must be rejected. On the basis of transfusion reaction and transplantation immunology, we hypothesized that allogeneic serum can inhibit tumor growth when injected intra-tumor. Initially, an in vitro cytotoxicity test was conducted using the C57BL/6 serum (intact or decomplemented) in combination with the BALB/c-originating CT26 cell line.  The CT26 cell line was used to establish a mouse model of colon cancer. When the tumor was palpable, C57BL/6 serum was injected intra-tumor. In addition to tumor size, hypoxia, metastatic capacity, angiogenesis, and metabolic and inflammatory status, we evaluated matrix metalloproteinase-2 (MMP)-2 and 9, vascular endothelial growth factor (VEGF)-A, Cluster of Designation (CD) 31, CD38 and interleukine (IL)-10. An in vitro experiment showed that heat-inactivated C57BL/6 serum had significantly lower cytotoxic effects on BALB/c-derived CT26 cells than intact C57BL/6 serum or BALB/c serum. In vivo experiments revealed that tumor size, HIF-1α, MMP-2, and MMP-9 levels were significantly lower in the experimental group than in the control group. In contrast to control animals, allogeneic serum treatment led to marked reductions in CD31, VEGF-1, CD38, and IL-10 levels. A new approach to serum or plasma therapy and allogeneic vaccines for cancer is intra-tumor injection of allogeneic serum. In light of the ease and availability of allogeneic immunotherapies, allogeneic serum and plasma therapy could potentially be used as an alternative monotherapy or in combination with other therapies.

    Abstract Breast cancer is one of the most common type of tumor and the leading cause of death in the world's female population. Various therapeutic approaches have been used to treat tumors but have not led to complete recovery and have even damaged normal cells in the body. Moreover, metastatic tumors such as breast cancer are much more resistant to treatment, and current treatments have not been very successful in treating them and remain a challenge. Therefore, new approaches should be applied to overcome this problem. Given the importance of hypoxia in tumor survival, we aimed to test the antitumor effects of oxygenated water to decrease hypoxia along with tumor-derived exosomes to target tumor. The purpose of administering oxygenated water and tumor exosomes was to reduce hypoxia and establish an effective immune response against tumor antigens, respectively. For this purpose, the breast cancer mice model was induced using the 4T1 cell line in Balb/c mice and treated with oxygenated water via an intratumoral (IT) and/or intraperitoneal (IP) route and/or exosome (TEX). Oxygenation via the IT+IP route was more efficient than oxygenation via the IT or IP route. The efficiency of oxygenation via the two routes along with TEX led to the best therapeutic outcome. Antitumor immune responses directed by TEX became optimized when systemic (IP) and local (IT) oxygenation was applied compared to administration of TEX alone. Results demonstrated a significant reduction in tumor size and the highest levels of IFN-

    Abstract Having played homeostatic role, the immune system maintains the integrity of the body. Such a characteristic makes immune system as an attractive candidate for resolution of inflammatory disease followed by tissue repair. As first responder cells, neutrophils direct immune response playing key role in tissue remodeling. Previous studies revealed that sperm attracts neutrophils and promotes uterine remodeling suitable for fetus growth. Accordingly, sperm and more efficiently sperm head had remodeling effects on damaged brain in Alzheimer's disease (AD) model. To further reveal the mechanism, two kinds of in vivo study, including kinetic study and inhibition of neutrophil phagocytosis on AD model, as well as in vitro study using co-culture of neutrophil and sperm head were performed. Kinetic study revealed that sperm head recruited neutrophil to nasal mucosa similar to that of uterus and sperm head-phagocytizing neutrophils acquired new activation status comparing to control. In vitro study also demonstrated that sperm head-phagocytizing neutrophils acquire new activation status and express coding RNAs of sperm head. Accordingly, inhibition of neutrophil phagocytic activity abrogated therapeutic effects of sperm head. Neutrophils activation status is important in the fate of inflammatory process. Modulation but not suppression of neutrophils helps remodeling and repair of damaged tissue. Sperm head is an intelligent cell and not just a simple particle to remove by phagocytosis but instead can program neutrophils and consequently immune response into reparative mode after phagocytosis.

    Abstract Microenvironmental elements can directly contribute to the induction and the maintenance of tumor. Oxygen is the main element in the cell microenvironment and hypoxia can affect the process of tumorigenesis. In response to hypoxia, cells change their pattern and characteristics. These changes suggest that it is not just adaptation, but some sort of cell defense against hypoxia. If hypoxia is corrected, then cell defense mechanisms are interrupted. An examination of the process of tumorigenesis helps to design better therapeutic strategies. A systematic review of the English literature was conducted by searching PubMed, Google Scholar, and ISI Web databases for studies on changes that defend and help cells to live in a hypoxic microenvironment. Cells respond to hypoxia by de-differentiation and an increase in heat shock proteins. Angiogenesis and deviation of inflammatory response in favor of hypoxic cell survival also defend and save the oxygen-starved cells from death. Finally, anti-angiogenic therapies and more hypoxia enhance metastasis, as tumors with low oxygen concentration are more malignant than tumors with high oxygen concentration. All these enable cells to migrate away from low oxygen areas and seek a more conducive microenvironment. Therapies that make the microenvironment more hypoxic need to be revised. This has been done for anti-angiogenic therapies, previously considered to be anti-tumor approaches. Effective therapies may be correcting therapies which direct the tumor microenvironment towards natural physical/chemical condition. Correcting therapies either bring back tumor cells to a normal form (correct tumor cells) or help the immune system to eradicate tumor cells which can not be corrected.

    Abstract The creation and development of the fetus is one of the wonders of nature and still has many unknowns. It was previously believed that the mother has no role in fetus formation/development and only acts as a chamber. Today, we know that the mother is involved in both formation and development of the fetus and even in the future of the baby's life. In this article, the relationship between some Qur'anic verses, Hadiths, and the results of new medical research on the importance of mother's role in the development of the fetus and future of the newborn life is discussed. It can be concluded that Qur'an and Hadiths are consistent with modern science in the issue discussed.

    Abstract Regulatory T cells (Tregs) profoundly affect tumor microenvironment and exert dominant suppression over antitumor immunity in response to self-antigen expressed by tumor. Immunotherapy targeting Tregs lead to a significant improvement in antitumor immunity. Intradermal injection of tumor antigen results in negative delayed-type hypersensitivity (DTH) type IV. However, anti-Tregs treatment/use of adjuvant along with tumor antigens turns DTH to positive. Considering Tregs as the earliest tumor sensor/responders, tumor can be regarded as Treg-mediated type IV hypersensitivity and negative DTH to tumor antigen is due to anti-inflammatory action of Tregs to tumor antigens at the injection site. Such a view would help us in basic and clinical situations to testify a candidate vaccine via dermal administration and evaluation of Treg proportion at injection site.
