The interplay of obesity, gut microbiome and diet in the immune check point inhibitors therapy era

Nikolaos Spyrou et al.

Summary: Immunotherapy has shown great promise in cancer treatment, but only a small percentage of patients exhibit lasting responses to immune checkpoint inhibitors. Factors such as obesity, host microbiome, and nutrition may play a role in influencing patients' response to immunotherapy, with emerging evidence suggesting that obese patients may actually benefit more from ICI therapy compared to those with a normal BMI. Further research is needed to explore how these factors can be leveraged to enhance the effectiveness of immunotherapy and potentially offer new therapeutic targets for cancer treatment.

Metabolic barriers to cancer immunotherapy

Kristin DePeaux et al.

Summary: The tumour microenvironment creates barriers that suppress immune responses, including physical barriers, recruitment of suppressive immune cells, and upregulation of inhibitory ligands on tumour cells. Therapies targeting metabolic restrictions in the tumour microenvironment show promise for combination therapies against various types of cancer.

Involvement of Oxidative Stress and the Innate Immune System in SARS-CoV-2 Infection

Evgenii M. Kozlov et al.

Summary: The emergence of the novel coronavirus in December 2019 in China led to a global pandemic that severely impacted healthcare systems and economic life worldwide. The virus primarily targets the respiratory system and causes severe acute respiratory syndrome, with most infected individuals being asymptomatic or having only minor symptoms, while those in high-risk groups have an increased likelihood of severe illness. Recent research has revealed the role of oxidative stress in SARS-CoV-2 infection, highlighting its potential importance in understanding the disease mechanism and developing treatment strategies.

Cancer metabolism and intervention therapy

Huakan Zhao et al.

Summary: Metabolic reprogramming with heterogeneity is a key feature of cancer, enabling tumor cells to adapt to low nutrition and hypoxic microenvironments. By manipulating various metabolic pathways, cancer cells produce biomass for their material needs and generate ATP and antioxidants to survive stress conditions. The metabolic products of cancer cells also play a role in remodeling the tumor microenvironment to create an immunosuppressive milieu. Targeting metabolic pathways may offer new therapeutic strategies for cancer treatment.

How could we forget immunometabolism in SARS-CoV2 infection or COVID-19?

Vijay Kumar

Summary: The COVID-19 pandemic has had a significant impact globally, with the immune system playing a crucial role in disease severity, particularly affecting older individuals and those with comorbidities. Protective antibodies produced by patients are not long-lasting, and therapeutic interventions may focus on regulating immunometabolism.
