Harnessing the Immunomodulatory Effects of Radiation Therapy.

In this article, we discuss the immunogenicity of radiation-induced cell death and describe the innate immune signaling pathways that precede adaptive antitumoral immunity. The innate and adaptive immune systems work in concert to generate systemic immune responses. In the setting of cancer, DNA damage caused by radiotherapy activates the innate immune system while tumor cell death liberates antigen that serves as a target for adaptive immunity. The immunomodulatory effects of radiation have been investigat...

Immuncheckpoint Inhibitors: Current Indications and Possible Future Concepts.

Different combination strategies of Immuncheckpoint inhibitors are currently undergoing clinical evaluation to further improve treatment outcomes. However, this has so far also been associated with a...

Immunomodulatory effects of BRAF and MEK Inhibitors: Implications for Melanoma therapy.

Targeted therapy with BRAF inhibitors (BRAFi) and MEK inhibitors (MEKi) provides rapid disease control with high response rates in patients with BRAF-mutant metastatic melanoma. However, the majority of patients develop resistance to therapy during the course of therapy. Immune checkpoint inhibitors show a slower onset of action with lower response rates, with responders showing sustained response. The combination of BRAFi/MEKi and immune checkpoint inhibitors combines the hope for a fast, reliable and last...

TrkB-Target Galectin-1 Impairs Immune Activation and Radiation Responses in Neuroblastoma: Implications for Tumour Therapy.

Galectin-1 (Gal-1) has been described to promote tumour growth by inducing angiogenesis and to contribute to the tumour immune escape. We had previously identified up-regulation of Gal-1 in preclinical models of aggressive neuroblastoma (NB), the most common extracranial tumour of childhood. While Gal-1 did not confer a survival advantage in the absence of exogenous stressors, Gal-1 contributed to enhanced cell migratory and invasive properties. Here, we review these findings and extend them by analyzing Ga...

A Combined Computer-Aided Approach to Drive the Identification of Potential Epitopes in Protein Therapeutics.

The identification of fragment sequences, or motifs, within a therapeutic protein that may elicit an immune response when processed by T-cells can be provided by computer-aided approaches. Immunogenicity is a significant problem associated with protein therapeutics and should be investigated in the early stage of protein-based drug development to avoid treatment resistance and potentially life-threatening immune responses.

Novel molecules have been developed and promising advances have been achieved in cancer therapy. The recent success of cancer immunotherapy clearly reflects the novelty of the approach and importance of this class of therapeutics. Due to the nature of immunotherapy, i.e., harnessing the patient's immune syst...

Checkpoint inhibitor colitis: a new model of inflammatory bowel disease?

Immune checkpoint inhibitors are monoclonal antibodies against the inhibitory, co-stimulatory molecules CTLA-4 and PD-1/PD-L1. Their use in oncology has been associated with frequent and diverse immune-related adverse events. In the digestive tract, such toxicity presents primarily as colonic inflammation, resembling inflammatory bowel disease (IBD). This review presents recent developments regarding the characteristics of checkpoint inhibitor colitis (CIC) and its relation to IBD.

Alpine soil microbial ecology in a changing world.

Climate change has a disproportionally large impact on alpine soil ecosystems, leading to pronounced changes in soil microbial diversity and function associated with effects on biogeochemical processes at the local and supraregional scales. However, due to restricted accessibility, high-altitude soils remain largely understudied and a considerable heterogeneity hampers the comparability of different alpine studies. Here, we highlight differences and similarities between alpine and arctic ecosystems, and we ...

Regulatory T cells: a potential target in cancer immunotherapy.

Cancer immunotherapy involving blockade of immune checkpoint molecules, such as CTLA-4 and PD-1, has shown remarkable clinical success across several types of malignancies. However, a fraction of patients experience disease progression after treatment; thus, exploring resistant mechanisms for immune checkpoint inhibitors and improving their treatment outcome with additional modalities are of great importance. CD4regulatory T (T) cells characterized by expression of the master regulatory transcription factor...
