Induced collagen type-I secretion by hepatocytes of the melanoma liver metastasis is associated with a reduction in tumour-infiltrating lymphocytes.

Background: Overall patients with melanoma liver metastasis (MLiM) have a dismal prognosis and poor responses to the standard of care treatment. Understanding the role of the tumour microenvironment (TME) is critical for discovering better strategies to overcome intrinsic therapy resistance in MLiM. The aim was to understand the crosstalk signalling pathways between hepatocytes and metastatic melanoma cells in the TME of MLiM.

Interferon-induced factor 16 is essential in metastatic melanoma to maintain STING levels and the immune responses upon IFN-γ response pathway activation.

Background: Immune checkpoint inhibitor (ICIs)-based therapies are the standard of care treatment for patients with metastatic melanoma (MM). The stimulator of interferon genes (STING) signaling pathway is critical in controlling immune responses to ICIs. Interferon (IFN)-γ-inducible protein 16 (IFI16) is a cytosolic DNA sensor that activates the STING signaling pathway.

Translational studies demonstrating the clinical utility and importance of cfmiRs in multiple cancers have significantly increased.

Effect of Different Wheat Sprouting Conditions on the Characteristics of Whole-Wheat Flour.

Research Background: Controlled sprouting promotes physiological and biochemical changes in whole grains, improves their nutritional value and offers technological advantages for breadmaking as an alternative to traditional whole grains. The aim of this study is to find sprouting conditions for the grains of Klein Valor wheat variety ( L.) that would increase the nutritional value without significantly affecting the gluten proteins, which are essential in wholegrain baked goods.

Interruption of the intratumor CD8 T cell:Treg crosstalk improves the efficacy of PD-1 immunotherapy.

PD-1 blockade unleashes potent antitumor activity in CD8 T cells but can also promote immunosuppressive T regulatory (Treg) cells, which may worsen the response to immunotherapy. Tumor-Treg inhibition is a promising strategy to improve the efficacy of checkpoint blockade immunotherapy; however, our understanding of the mechanisms supporting tumor-Tregs during PD-1 immunotherapy is incomplete. Here, we show that PD-1 blockade increases tumor-Tregs in mouse models of melanoma and metastatic melanoma patients.

Facilitators and barriers to implementing complex community-based interventions for addressing acute malnutrition in low- and lower-middle income countries: A scoping review.

Community-based nutrition interventions have been established as the standard of care for identifying and treating acute malnutrition among children 6-59 months in low- and lower-middle-income countries. However, limited research has examined the factors that influence the implementation of the community-based component of interventions that address severe acute malnutrition and moderate acute malnutrition among children. The objective of this review was to identify and describe the facilitators and barriers in implementing complex community-based nutrition interventions to address acute malnutrition among children in low- and lower-middle-income countries.

Targeting IL-6 trans-signalling by sgp130Fc attenuates severity in SARS-CoV-2 -infected mice and reduces endotheliopathy.

Background: SARS-CoV-2 infection is considered as a relapsing inflammatory process with a dysregulation of IL-6 signalling. Classic IL-6 signalling is thought to represent a defence mechanism against pathogens. In contrast, IL-6 trans-signalling has pro-inflammatory effects.
