Loss of Y in regulatory T lymphocytes in the tumor micro-environment of primary colorectal cancers and liver metastases.

Male sex is a risk factor for colorectal cancer (CRC) with higher illness burden and earlier onset. Thus, we hypothesized that loss of chromosome Y (LOY) in the tumor micro-environment (TME) might be involved in oncogenesis. Previous studies show that LOY in circulating leukocytes of aging men was associated with shorter survival and non-hematological cancer, as well as higher LOY in CD4 + T-lymphocytes in men with prostate cancer vs.

The thick-borne encephalitis caused by alimentary transmission - case series report.

Tick-borne encephalitis (TBE) is a central nervous system zoonotic disease transmitted by ticks. Tick-borne encephalitis virus (TBEV) is one of the main causes of lymphocytic meningitis in the areas of its endemic occurrence. A mode of transmission of TBEV which is rarely observed in clinical practice is an alimentary transmission through consumption of unpasteurised dairy products from infected animals.

Study of the first clinical cases on monkeypox in Poland.

Monkeypox is a viral, zoonotic, emerging infectious disease that has become the most significant orthopoxviral infection among humans since the eradication of smallpox. It is endemic in Central and West Africa, and since May 2022 it has caused a multi-country outbreak in six continents. So far, no clinical cases of this disease have been observed in Poland.

Animal unit hygienic conditions influence mouse intestinal microbiota and contribute to T-cell-mediated colitis.

Inflammatory bowel disease (IBD) is a group of chronic inflammatory disorders of the gastrointestinal tract with worldwide increasing incidence. Recent studies indicate that certain species of intestinal bacteria are strongly associated with IBD. Helper T lymphocytes are not only the key players in mediating host defense against a wide variety of pathogens but also contribute to pathogenesis of many immune-related diseases.

Lung Transplant in a Patient With Multifocal Langerhans Cell Histiocytosis After Chemotherapy With Cladribine: A Case Report.

Langerhans cell histiocytosis (LCH) is a rare inflammatory disorder of myeloid dendritic cells with mutations involving KRAS, BRAF and/or NRAS, and MAP2K1 genes. We describe the case of a 58-year-old female previous smoker with multifocal LCH involving the lungs, pituitary gland and mandibular bone. Initial treatment with 6 cycles of cladribine showed improvement in her extrapulmonary lesions, however, her lung disease progressed and after qualification and assessment tests she underwent uncomplicated double lung transplant surgery and was discharged home.

Comprehensive cancer-oriented biobanking resource of human samples for studies of post-zygotic genetic variation involved in cancer predisposition.

The progress in translational cancer research relies on access to well-characterized samples from a representative number of patients and controls. The rationale behind our biobanking are explorations of post-zygotic pathogenic gene variants, especially in non-tumoral tissue, which might predispose to cancers. The targeted diagnoses are carcinomas of the breast (via mastectomy or breast conserving surgery), colon and rectum, prostate, and urinary bladder (via cystectomy or transurethral resection), exocrine pancreatic carcinoma as well as metastases of colorectal cancer to the liver.

Kinomics platform using GBM tissue identifies BTK as being associated with higher patient survival.

Better understanding of GBM signalling networks in-vivo would help develop more physiologically relevant ex vivo models to support therapeutic discovery. A "functional proteomics" screen was undertaken to measure the specific activity of a set of protein kinases in a two-step cell-free biochemical assay to define dominant kinase activities to identify potentially novel drug targets that may have been overlooked in studies interrogating GBM-derived cell lines. A dominant kinase activity derived from the tumour tissue, but not patient-derived GBM stem-like cell lines, was Bruton tyrosine kinase (BTK).

The effects of RNA editing in cancer tissue at different stages in carcinogenesis.

RNA editing is one of the most prevalent and abundant forms of post-transcriptional RNA modification observed in normal physiological processes and often aberrant in diseases including cancer. RNA editing changes the sequences of mRNAs, making them different from the source DNA sequence. Edited mRNAs can produce editing-recoded protein isoforms that are functionally different from the corresponding genome-encoded protein isoforms.

The 12-week double-blind treatment period consisted of a 6-week titration phase and a 6-week maintenance phase.

Adoptive Cell Therapy-Harnessing Antigen-Specific T Cells to Target Solid Tumours.

In recent years, much research has been focused on the field of adoptive cell therapies (ACT) that use native or genetically modified T cells as therapeutic tools. Immunotherapy with T cells expressing chimeric antigen receptors (CARs) demonstrated great success in the treatment of haematologic malignancies, whereas adoptive transfer of autologous tumour infiltrating lymphocytes (TILs) proved to be highly effective in metastatic melanoma. These encouraging results initiated many studies where ACT was tested as a treatment for various solid tumours.
