VEGF in psoriatic arthritis: Systematic review and meta-analysis.

Psoriatic arthritis (PsA), a chronic autoimmune disease of unclear aetiology, is associated with dysregulated angiogenesis due to the proliferation, migration, and differentiation of endothelial cells. Vascular endothelial growth factor (VEGF) plays a key role such that PsA patients exhibit skin and joint symptoms, e.g.

Vascular endothelial growth factor in inflammatory bowel disease: A systematic review and meta-analysis.

Aim: Vascular endothelial growth factor (VEGF) is linked to inflammation and angiogenesis, indicating a possible role in inflammatory bowel disease (IBD) and its main clinical manifestations, Crohn's disease (CD) and ulcerative colitis (UC). This systematic review and meta-analysis investigated studies assessing circulating VEGF concentrations in IBD patients and healthy controls, considering the effect of IBD type, sample type and geographical location.

Methods: A systematic search identified 18 studies (28 group comparators) investigating 1741 IBD patients and 1291 controls.

Higher scores of the Kessler Psychological Distress Scale (K10) are associated with lower serum ergothioneine and higher serum asymmetric dimethyl-l-arginine concentrations in a cohort of middle-aged and older adults.

Background: Ergothioneine (ERT) and asymmetric dimethyl-l-arginine (ADMA) have been associated with cognitive decline and dementia in older adults, but their interplay with psychological distress remains unexplored. This study aimed to measure the serum concentrations of ERT and ADMA in a representative sample of older community-dwelling adults and to determine their association with psychological distress.

Methods: Data on clinical, lifestyle, demographic characteristics, and serum concentrations of ERT and ADMA were collected from a population-based sample of older Australian adults (mean age 65.

Investigating bilirubin concentrations in schizophrenia: A systematic review and meta-analysis.

Schizophrenia, a severe mental disorder characterized by chronic disability and poor quality of life, has been shown to be associated with alterations in redox balance. Recent research has suggested a potential link between the antioxidant bilirubin and schizophrenia, although findings have been inconsistent. To address this gap, we conducted a systematic review and meta-analysis to evaluate possible alterations in bilirubin concentrations in schizophrenia.

The association between bilirubin concentrations and inflammatory bowel disease: Insights from a systematic review and meta-analysis.

Background: Inflammatory bowel disease (IBD), including Crohn's disease (CD) and ulcerative colitis (UC), poses a significant challenge to health care systems because of its chronic nature and increasing global prevalence. Effective management of IBD requires accurate diagnostic tools and biomarkers. This systematic review and meta-analysis aimed to evaluate the relationship between bilirubin concentrations and IBD activity and outcomes.

The relationship between haemoglobin concentrations and obstructive sleep apnea syndrome: A systematic review and meta-analysis.

Background: This systematic review and meta-analysis investigates the relationship between haemoglobin (Hb) concentrations and obstructive sleep apnea syndrome (OSAS).

Methods: Following PRISMA guidelines, we searched PubMed, EMBASE, and Cochrane Library from inception to March 8, 2024. Eligible studies included cross-sectional, cohort, and case-control designs comparing Hb concentrations in OSAS patients and healthy controls.

Association between blood Pentraxin-3 concentrations and rheumatic diseases: A systematic review and meta-analysis.

Background: Among the Pentraxins, the long Pentraxin-3 (PTX-3) is associated with several processes, particularly in the earliest phases of the innate humoral response. Increased blood PTX-3 concentrations have been observed in a wide range of conditions, from infectious to cardiovascular disorders. Since its increase is more rapid than C-reactive protein (CRP), PTX-3 can be useful to detect and monitor early inflammation.

Pulmonary Involvement in Recurrent Respiratory Papillomatosis: A Systematic Review.

Recurrent respiratory papillomatosis (RRP) is a non-malignant disease, characterized by the production of wart-like growths in the respiratory tract, affecting both young people and adults (juvenile-onset recurrent respiratory papillomatosis, JORRP, and adult-onset recurrent respiratory papillomatosis, AORRP, respectively). Infection caused by human papillomavirus (HPV) is known as the main factor involved in RRP development. Complications of RRP may rarely occur, including lung involvement and malignant transformation.

Association between Red Blood Cell Distribution Width and Obstructive Sleep Apnea Syndrome: A Systematic Review and Meta-Analysis.

Although polysomnography is the gold standard method to diagnose obstructive sleep apnea syndrome (OSAS), there is an ongoing quest for simpler and relatively inexpensive biomarkers of disease presence and severity. To address this issue, we conducted a systematic review of the potential diagnostic role of the red blood cell distribution width (RDW), a routine hematological parameter of red blood cell volume variability, in OSAS. A total of 1478 articles were initially identified in the databases PubMed, Web of Science, Scopus, Embase, and Google Scholar, from their inception to February 2023, and 20 were selected for final analysis.

Natural history of type 1 diabetes on an immunodysregulatory background with genetic alteration in B-cell activating factor receptor: A case report.

The immunological events leading to type 1 diabetes (T1D) are complex and heterogeneous, underscoring the necessity to study rare cases to improve our understanding. Here, we report the case of a 16-year-old patient who showed glycosuria during a regular checkup. Upon further evaluation, stage 2 T1D, autoimmune thrombocytopenic purpura (AITP), and common variable immunodeficiency (CVID) were diagnosed.

Prevalence of Human Papilloma Virus Infection in Bladder Cancer: A Systematic Review.

The etiology of bladder cancer is known to be associated with behavioral and environmental factors. Moreover, several studies suggested a potential role of HPV infection in the pathogenesis with controversial results. A systematic review was conducted to assess the role of HPV.

Follicular helper T cell signature of replicative exhaustion, apoptosis, and senescence in common variable immunodeficiency.

Common variable immunodeficiency (CVID) is the most frequent primary antibody deficiency whereby follicular helper T (Tfh) cells fail to establish productive responses with B cells in germinal centers. Here, we analyzed the frequency, phenotype, transcriptome, and function of circulating Tfh (cTfh) cells in CVID patients displaying autoimmunity as an additional phenotype. A group of patients showed a high frequency of cTfh1 cells and a prominent expression of PD-1 and ICOS as well as a cTfh mRNA signature consistent with highly activated, but exhausted, senescent, and apoptotic cells.

NKp46-expressing human gut-resident intraepithelial Vδ1 T cell subpopulation exhibits high antitumor activity against colorectal cancer.

γδ T cells account for a large fraction of human intestinal intraepithelial lymphocytes (IELs) endowed with potent antitumor activities. However, little is known about their origin, phenotype, and clinical relevance in colorectal cancer (CRC). To determine γδ IEL gut specificity, homing, and functions, γδ T cells were purified from human healthy blood, lymph nodes, liver, skin, and intestine, either disease-free, affected by CRC, or generated from thymic precursors.

High-throughput analysis of the human thymic Vδ1 T cell receptor repertoire.

γδ T cells are a relatively rare subset of lymphocytes in the human peripheral blood, but they play important roles at the interface between the innate and the adaptive immune systems. The γδ T cell lineage is characterized by a signature γδ T cell receptor (γδTCR) that displays extensive sequence variability originated by DNA rearrangement of the corresponding V(D)J loci. Human γδ T cells comprise Vγ9Vδ2 T cells, the major subset in the peripheral blood; and Vδ1 T cells, the predominant subpopulation in the post-natal thymus and in peripheral tissues.

Broad Cytotoxic Targeting of Acute Myeloid Leukemia by Polyclonal Delta One T Cells.

Acute myeloid leukemia (AML) remains a clinical challenge due to frequent chemotherapy resistance and deadly relapses. We are exploring the immunotherapeutic potential of peripheral blood Vδ1 T cells, which associate with improved long-term survival of stem-cell transplant recipients but have not yet been applied as adoptive cell therapy. Using our clinical-grade protocol for expansion and differentiation of "Delta One T" (DOT) cells, we found DOT cells to be highly cytotoxic against AML primary samples and cell lines, including cells selected for resistance to standard chemotherapy.

Molecular Determinants of Target Cell Recognition by Human γδ T Cells.

The unique capabilities of gamma-delta (γδ) T cells to recognize cells under stressed conditions, particularly infected or transformed cells, and killing them or regulating the immune response against them, paved the way to the development of promising therapeutic strategies for cancer and infectious diseases. From a mechanistic standpoint, numerous studies have unveiled a remarkable flexibility of γδ T cells in employing their T cell receptor and/or NK cell receptors for target cell recognition, even if the relevant ligands often remain uncertain. Here, we review the accumulated knowledge on the diverse mechanisms of target cell recognition by γδ T cells, focusing on human γδ T cells, to provide an integrated perspective of their therapeutic potential in cancer and infectious diseases.
