Article Synopsis
  • * Researchers explored dual-targeting strategies by combining anti-CD19 and anti-BCMA CAR-T cells to enhance effectiveness, optimizing various co-transduction methods and demonstrating improved targeting of tumor cells with the new approach, ARI0003.
  • * A first-in-human trial (CARTD-BG-01, NCT06097455) has been launched to assess the safety and efficacy of ARI0003, which was manufactured under strict conditions to lower the risk of genotoxicity.

Article Synopsis
  • The study examined antibody levels in 200 unvaccinated hospital workers with mild COVID-19, focusing on IgA and IgG against SARS-CoV-2 proteins.
  • Differences in antibody titers were noted based on factors like time after infection, age, sex, and symptoms, with higher IgG and IgA levels seen in those testing positive for IgM.
  • A correlation was found between antibody levels and symptom severity, with certain antibodies decreasing over time after infection.

Immune checkpoint inhibitors (ICI) have the potential to trigger unpredictable immune-related adverse events (irAEs), which can be severe. The underlying mechanisms of these events are not fully understood. As PD-L1 is upregulated by IFN, the heightened immune activation resulting from PD-1/PD-L1 inhibition may enhance the IFN response, triggering the expression of IFN-inducible genes and contributing to irAE development and its severity.

Several products containing chimeric antigen receptor T cells targeting CD19 (CART19) have been approved for the treatment of patients with relapsed/refractory non-Hodgkin's lymphoma (NHL) and acute lymphoblastic leukaemia (ALL). Despite very impressive response rates, a significant percentage of patients experience disease relapse and die of progressive disease. A major cause of CART19 failure is loss or downregulation of CD19 expression in tumour cells, which has prompted a myriad of novel strategies aimed at targeting more than one antigen (e.

Varnimcabtagene autoleucel (var-cel) is an academic anti-CD19 chimeric antigen receptor (CAR) product used for the treatment of non-Hodgkin lymphoma (NHL) in the CART19-BE-01 trial. Here we report updated outcomes of patients with NHL treated with var-cel. B-cell recovery was compared with patients with acute lymphoblastic leukaemia (ALL).

Non-absorbable polypropylene (PP) meshes have been widely used in surgical reconstruction of the pelvic floor disorders. However, they are associated with serious complications. Human acellular dermal matrices (hADM) have demonstrated safety and efficacy in reconstructive medicine, but their suitability and efficacy at vaginal level is not known.

Immune-related adverse events (irAEs) are unpredictable autoimmune-like toxicities induced by immune checkpoint inhibitors (ICI). irAEs are a consequence of a breakdown in self-tolerance. ICIs can induce autoantibody formation, and the presence of antinuclear autoantibodies (ANAs) has been reported in patients who developed irAEs.

It is essential to find new biomarkers for severity stratification of patients with coronavirus disease (COVID-19). Growth differentiation factor 15 (GDF-15) is upregulated in pathological conditions that involve inflammation and/or oxidative stress. We determined circulating levels of GDF-15 and correlated them with clinical and laboratory parameters reflecting severity in 84 patients with COVID-19, finding that GDF-15 levels were higher in both patients than in 20 healthy controls and were higher in patients with poorer respiratory function.

Objectives: Anti-TIF-1γ autoantibody detection is important for cancer screening in patients with dermatomyositis. The gold standard for anti-TIF-1γ detection, immunoprecipitation, is only available from a few specialized laboratories worldwide, so commercial ELISA/immunoblot tests have emerged in recent years. To analyze their usefulness in diagnosing cancer-associated dermatomyositis, we compared Euroimmun Euroline profile with our previously validated in-house immunoblot assay with human recombinant TIF-1γ.

Article Synopsis
  • * Researchers compared these blood cell complexes in healthy people and patients with lung cancer, finding that cancer patients had higher levels of them.
  • * Certain patterns in the levels of these cell complexes can help doctors understand which patients might face more severe side effects, helping improve care for those receiving the treatment.

Synopsis of recent research by authors named "Leticia Alserawan"

  • - Leticia Alserawan's recent research primarily focuses on the immune response in various conditions, particularly examining antibody responses in COVID-19 patients and the mechanisms behind immune-related adverse events related to immune checkpoint inhibitors (ICIs).
  • - A significant finding from her work on COVID-19 indicates the correlation between IgA and IgG titers against SARS-CoV-2 proteins and the severity of symptoms in mild infection cases, highlighting the importance of understanding immune profiles even in asymptomatic cases.
  • - Additionally, Alserawan's research has explored the predictive markers of immune-related adverse events in cancer therapy, providing insights into the involvement of circulating leukocyte-platelet complexes and autoantibody formation during treatment with ICIs, which can lead to severe autoimmune reactions.
