The pathogenesis and progression of follicular lymphoma (FL) depends on immune evasion mechanisms. The gut microbiota has been reported to be associated with the development and outcome of several human diseases by modulating host immunity. Thus, the present study investigated the characteristics and prognostic value of the gut microbiota in FL. Fecal samples from treatment-naïve patients with FL (n=28) and healthy controls (n=18) were prospectively collected. The gut microbiota diversity and composition were examined by 16S ribosomal RNA sequencing. The results demonstrated that patients with FL had distinct microbiota compositions. The relative abundance of the family was significantly increased in patients with FL (P=0.01). Furthermore, a high level of was identified as a strong indicator of tumor burden (P=0.001), and was related to the FL International Prognostic Index score and serum lactate dehydrogenase levels. The present results indicated an association between the gut microbiota and FL prognosis. Findings from the present study may provide a rational foundation for further investigation of the role of gut microbiota in lymphoma management.

The microbiome-gut-testis axis has emerged as a significant area of interest in understanding testicular cancer, particularly testicular germ cell tumors (TGCTs), which represent the most common malignancy in young men. The interplay between the gut and testicular microbiomes is hypothesized to influence tumorigenesis and reproductive health, underscoring the complex role of microbial ecosystems in disease pathology. The microbiome-gut-testis axis encompasses complex interactions between the gut microbiome, systemic immune modulation, and the local microenvironment of the testis.

The gut barrier encompasses several interactive, physical, and functional components, such as the gut microbiota, the mucus layer, the epithelial layer and the gut mucosal immunity. All these contribute to homeostasis in a well-regulated manner. Nevertheless, this frail balance might be disrupted for instance by westernized dietary habits, infections, pollution or exposure to antibiotics, thus diminishing protective immunity and leading to the onset of chronic diseases.

Introduction: The gut microbiota plays a pivotal role in influencing host health, through the production of metabolites and other key signalling molecules. While the impact of specific metabolites or taxa on host cells is well-documented, the broader impact of a disrupted microbiota on immune homeostasis is less understood, which is particularly important in the context of the increasing overuse of antibiotics.
Methods: Female C57BL/6 mice were gavaged twice daily for four weeks with Vancomycin, Polymyxin B, or PBS (control).

Background: Dysbiosis of the lung microbiome can contribute to the initiation and progression of lung cancer. Synchronous multiple primary lung cancer (sMPLC) is an increasingly recognized subtype of lung cancer characterized by high morbidity, difficulties in early detection, poor prognosis, and substantial clinical challenges. However, the relationship between sMPLC pathogenesis and changes in the lung microbiome remains unclear.
