Combining T cell receptor sequencing and transcriptomics to characterize tissue-resident T cells from human gut biopsies.

Gastrointestinal T cells (GI-T) play a critical role in mucosal immunity, balancing tolerance and pathogen defence. T cells recognize antigens via T cell receptors (TCRs). Next-generation sequencing (NGS) is utilized to analyse TCR repertoires in contexts such as health, haematological diseases, autoimmunity, and inflammation.

Digitalization and Standardization Oncology Drug Therapy Plans with the Onkopti Database for Online Publication and Import into Software.

Background: Oncological therapy is based on multidimensional therapy protocols. The requirements for standardized protocols and digitation are high. These protocols are created through several complex development stages to ensure standardized recording.

Shape of the art: TCR-repertoire after allogeneic hematopoietic cell transplantation.

The human adaptive immune repertoire is characterized by specificity and diversity to provide immunity against past and future tasks. Such tasks are mainly infections but also malignant transformations of cells. With its multiple lines of defense, the human immune system contains both, rapid reaction forces and the potential to capture, disassemble and analyze strange structures in order to teach the adaptive immune system and mount a specific immune response.

Endocrine health in survivors of adult-onset cancer.

Long-term survivors of cancer (ie, the patient who is considered cured or for whom the disease is under long-term control and unlikely to recur) are at an increased risk of developing endocrine complications such as hypothalamic-pituitary dysfunctions, hypogonadisms, osteoporosis, or metabolic disorders, particularly when intensive tumour-directed therapies are applied. Symptom severity associated with these conditions ranges from mild and subclinical to highly detrimental, affecting individual health and quality of life. Although they are usually manageable, many of these endocrine pathologies remain underdiagnosed and untreated for years.

Potential of TCR sequencing in graft-versus-host disease.

Graft-versus-host disease (GvHD) remains one of the major complications following allogeneic haematopoietic stem cell transplantation (allo-HSCT). GvHD can occur in almost every tissue, with the skin, liver, and intestines being the mainly affected organs. T cells are implicated in initiating GvHD.

Established and Emerging Treatments of Skin GvHD.

Graft-versus-host disease (GvHD) of the skin is a severe allo-immune reaction and complication following allogeneic stem cell transplantation. Over the past years, intensive pre-clinical research has led to an improved understanding of the pathophysiology of acute and to a lesser extend chronic GvHD. This has translated into the approval of several new agents for the treatment of both forms of GvHD.

Skeletal health in patients following allogeneic hematopoietic cell transplantation.

Allogeneic hematopoietic cell transplantation (HCT) is a potentially curative approach for patients with certain hematological diseases, including several forms of lymphoma and leukemia. Besides several treatment-associated risks, transplanted patients are at an increased risk of developing osteoporosis. The underlying pathophysiology is complex and includes factors influenced directly by the disease as well as applied therapies like irradiation, chemotherapy and adjuvant immunosuppressive agents.

T-cell receptor-α repertoire of CD8+ T cells following allogeneic stem cell transplantation using next-generation sequencing.

Alloreactivity or opportunistic infections following allogeneic stem cell transplantation are difficult to predict and contribute to post-transplantation mortality. How these immune reactions result in changes to the T-cell receptor repertoire remains largely unknown. Using next-generation sequencing, the T-cell receptor alpha (TRα) repertoire of naïve and memory CD8 T cells from 25 patients who had received different forms of allogeneic transplantation was analyzed.
