Monomorphic epitheliotropic intestinal T-cell lymphoma (MEITL) is a primary intestinal T-cell lymphoma and other organ involvement is very rare. A rare case of MEITL involving the lung and brain is herein reported. The patient developed panperitonitis with a small intestinal perforation, and emergency surgery was performed. The pathological findings from the surgical specimens demonstrated atypical lymphoid cells which were positive for CD3, CD8, and CD56. Moreover, the pathological findings of lung specimens taken by bronchoscopy were consistent with those of the small intestine. It is therefore important to include the possibility of MEITL in the differential diagnosis of cancer patients.

Metabolic dysfunction-associated steatohepatitis (MASH) is characterized by severe liver inflammation and fibrosis due to an imbalanced immune response caused by enhanced bacterial components. The progression of MASH is closely linked to increased permeability of intestinal mucosal barrier facilitating enter of bacterial components into hepatic portal venous system. B cells are important immune cells for adaptive responses and enhance hepatic inflammation through cytokine production and T cell activation.

Here, we investigated the relationship between the attenuation of lung cancer growth due to oral administration of Euglena gracilis water extract (EWE) and T cell stimulation. Orally administered EWE was revealed to increase PD-1 and PD-L1 mRNA and proteins primarily in tumor-infiltrating lymphocytes (TILs), which was correlated with a significant decrease in the tumor weights in mice. A combination treatment with EWE and anti-PD-1 antibody significantly decreased the growth of murine lung tumors more than treatment with either alone by increasing the number of TILs and attenuating T cell exhaustion.

Background: Lysinuric protein intolerance (LPI) is a metabolic disorder that leads to dysfunctional intestinal absorption and kidney clearance of cationic amino acids. Chronic kidney disease develops in many LPI patients and leads to end-stage kidney disease in at least 10% of patients. Since data on kidney transplants in LPI patients are limited, we analysed the outcomes of LPI patients after transplantation in Finland.

Background And Aims: Refractory celiac disease type II (RCDII) is characterized by a clonally expanded aberrant cell population in the small intestine. The role of other tissue-resident immune subsets in RCDII is unknown. Here, we characterized CD8 and CD4 T cells in RCDII duodenum at the single-cell level and .

Objective: Studies in mouse models and human adults have shown that the intestinal microbiota composition can affect peripheral immune cells. We here examined whether the gut microbiota compositions affect B and T-cell subsets in children.
Methods: The intestinal microbiota was characterized from stool samples of 344 10-year-old children from the Generation R Study by performing 16S rRNA sequencing.
