Ovarian transplantation might be possible in future

Approximately 11% of women worldwide suffer from premature ovarian failure. Because of the advances in modern cancer therapy, the number of young women surviving cancer is on the increase. However, in most cases, no specific cause can be identified. Now, for the first time, an international team of researchers has successfully transplanted an ovary from one individual to another, even managing to restore a monthly cycle.

Discussion MDSCs violently emerge in pathological conditions in an attempt to limit potentially harmful immune and inflammatory responses. Mechanisms supporting their expansion and survival are deeply investigated in cancer, in the perspective to reactivate specific antitumor responses and prevent their contribution to disease evolution. These findings will likely contribute to improve the targeting of MDSCs in anticancer immunotherapies, either alone or in combination with immune checkpoint inhibitors. New evidence indicates that the expansion of myeloid cell differentiation in pathology is subject to fine-tuning, as its...

Conclusions Several model systems are now available to characterize the MSC-tumour interplay in the TME. These offer early promise in establishing robust preclinical platforms for the identification of crucial molecular pathways and for the assessment of clinical efficacy of novel drugs to inhibit cancer development and progression. However, selection of the right model for a given study should be shaped on the purpose, and should also consider fixed biological, biochemical, and biophysical parameters according to the specific tumour type. Finally, in order to get reliable and useful results to be translated to the clinic...

Conclusion Several TISC-based immunotherapeutic approaches are under development in various stages of preclinical studies. As outlined in this review article, a careful and more exhaustive genetic and metabolic understanding of TISC-associated phenotypes is critical to develop novel TISC based immunotherapies. Various components within the tumor microenvironment such as tumor cells, infiltrating immune cells, and supporting stromal cells impact the TISC metabolism. This unique metabolic profile leads to upregulation of certain enzymes and proteins such as ALDH1, CEP55, IDO COA1 etc., which can be utilized for development ...

Conclusions and Perspectives In this review, we have discussed important milestones from the early description of “Serum-sickness” as being due to antibodies directed against Neu5Gc epitopes all the way to the present-day therapeutic implications of these antibodies in cancer therapy. Some of these milestones have been represented in a concise timeline (Figure 6). While the “Xenosialitis” hypothesis is well-supported in the human-like mouse models, it has yet to be conclusively proven in humans. It remains to be seen if “Xenosialitis” plays a role in other uniquely-human diseases. FI...

In this study, T cells deficient in TRAF6 display enhanced T cell activation, CD28-indpendent stimulation and resistance to Treg cell-mediated suppression (176). Although TLR signaling can promote T cell resistance to Treg cells, the precise molecular mechanism remains yet to be elucidated. It is worth noting that TLR stimulation of T cells increases cytokine production (173, 177), thus future studies should delineate the effect of TLR-MyD88 signaling vs. subsequently induced cytokines in generating resistance to Treg cells. Lastly, it is also crucial to evaluate the effect of TLR signaling on regulatory T cells which also...

Discussion Suppressor of cytokine signaling 1 is an essential molecule for maintaining immune homeostasis and subverting inflammation. Disorders arising from excess inflammation or SOCS1 deficiency can be potentially treated with SOCS1 mimetics (Ahmed et al., 2015). While SOCS1 has promising potential in many disorders, it should be noted that new targets and actions of SOCS1 are still being discovered and not all the effects of this protein are beneficial in autoimmune diseases and cancer. For instance, SOCS1 degrades IRS1 and IRS2, required for insulin signaling, via the SOCS Box domain, thus, limiting its potential in ...

Authors: Abstract The diagnosis of cancer in females younger than 20 years is rare, with the incidence of 17 cases per 100,000 individuals per year in the United States. Although advancements in cancer therapy have dramatically improved childhood cancer survival, gynecologists should be aware of the increased risk of adverse reproductive health effects from each type of therapy. Cancer and its treatment may have immediate or delayed adverse effects on reproductive health. Gynecologists may be consulted for the following issues: pubertal concerns; menstrual irregularities; heavy menstrual bleeding and anemia; sexu...

Scientists at the Vaccine and Immunotherapy Center (VIC) at Massachusetts General Hospital have uncovered a novel, two-agent immunotherapy combination that worked surprisingly well in animal models with malignant mesothelioma. The discovery has sparked new optimism for immunotherapy, which has struggled to provide consistently positive results with aggressive cancers such as mesothelioma. “This is the beginning of a new story of hope, a new combination of immunotherapy,” Dr. Mark Poznansky, director of the VIC and associate professor at Harvard Medical School, told Asbestos.com. “It worked quite well in a...
