This study highlights how the use of in vitro 3D model can allow rapid screening and selection of new and safer drugs. Introduction Angiogenesis is a complex and finely regulated process that consists of the growth of new capillary blood vessels from pre-existing vessels to create communication pathways among tissues. The coordination of different activities such as endothelial cell proliferation and migration, metalloproteinase function, integrin expression and pericyte stabilization is essential for angiogenesis (Folkman, 1984). The “angiogenic switch” is “on” when the balance between pro-...

The selected activation of photosensitizers in cancer cells is highly desired to overcome this problem. We...

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 ...

Kandalaft* Department of Oncology, Center for Experimental Therapeutics, Ludwig Center for Cancer Research, University of Lausanne, Lausanne, Switzerland With the advent of combined immunotherapies, personalized dendritic cell (DC)-based vaccination could integrate the current standard of care for the treatment of a large variety of tumors. Due to their proficiency at antigen presentation, DC are key coordinators of the innate...

Conclusion In this article, we use the amphiphilic copolymer DSPE-SS-mPEG, which is connected by disulfide bonds. Afterward, the magnetic Fe3O4 nanoparticles and the hydrophobic drug are made by the self-assembly of the amphiphilic copolymer. DOX is encapsulated in the amphiphilic copolymer to form a magnetic nano drug controlled release system which is sensitive and responds to a reducing environment. This controlled release system can dissociate the disulfide bonds in the presence of dithiothreitol, thereby triggering the release system to disintegrate and expel the drug. When the DOX-loaded nanocarrier is transported ...

Conclusion: These new findings indicated that the CCL2/CCR2 axis promoted the progression of SACC cells via recruiting and reprogramming TAMs. Targeting TAMs by blocking the CCL2/CCR2 axis might be a prospective strategy for SACC therapy. Introduction Salivary adenoid cystic carcinoma (SACC) is one of the most commonly diagnosed salivary gland malignancies, accounting for about 10% of all salivary gland neoplasms (1, 2). The typical characteristics of SACC include the recurrent growth, aggressive invasion, hematogenous metastasis, and chemotherapy refractory (2–4). Despite the great efforts paid in the treatm...

In conclusion, this study demonstrates that WG-391D exhibits strong antitumor activity against ovarian cancer and indicates that the down-regulation of CDC25B by inhibitors could provide a rationale for ovarian cancer therapy. Introduction Ovarian cancer is one of the most common malignances in females. The American Cancer Society estimated that there were 22,240 cases of ovarian cancer, and 14,070 deaths, in the United States in 2018 (1). During its early stages, ovarian cancer can be asymptomatic; hence, ~70% of patients have advanced disease when diagnosed and ultimately develop chemotherapeutic drug resistance an...
