White blood cells have a potential role in the pathogenesis of vasculopathy in diabetic patients. We studied the circulating peripheral blood in a cohort of patients with documented ischemic heart or brain disease with and without type 2 diabetes by means of image analysis and flow cytometry. Our study showed that the state of leukocyte adhesiveness/aggregation is slightly increased in those who had concomitant diabetes but that there was no difference regarding the expression of CD11b/CD18 and CD62L antigens on the surface of the peripheral blood white blood cells. The finding of a significantly increased number of white blood cells in the peripheral blood of patients with ischemic vascular diseases is important insofar as it is associated with a poorer prognosis.

The phase 2 CLL2-BZAG trial tested a measurable residual disease (MRD)-guided combination treatment of zanubrutinib, venetoclax and obinutuzumab after an optional bendamustine debulking in patients with relapsed/refractory CLL. In total, 42 patients were enrolled and two patients with ≤2 induction cycles were excluded from the analysis population per protocol. Patients had a median of one prior therapy (range 1-5), 18 patients (45%) had already received a BTK inhibitor (BTKi), seven patients (17.

Β-thalassemia is one of the global health burdens. The CD41-42 (-TCTT) mutation at HBB is the most prevalent pathogenic mutation of β-thalassemia in both China and Southeast Asia. Previous studies focused on repairing the HBB CD41-42 (-TCTT) mutation in β-thalassemia patient-specific induced pluripotent stem cells, which were subsequently differentiated into hematopoietic stem and progenitor cells (HSPCs) for transplantation.

Autosomal dominant polycystic kidney disease (ADPKD) is a dominant genetic disorder caused primarily by mutations in the PKD1 gene, resulting in the formation of numerous cysts and eventually kidney failure. However, there are currently no gene therapy studies aimed at correcting PKD1 gene mutations. In this study, we identified two mutation sites associated with ADPKD, c.

Enzyme-linked immunosorbent spot analysis is frequently used to investigate immune responsiveness during clinical trials. However, ELISpot classically utilizes peripheral blood mononuclear cell isolates from whole blood, requiring relatively high blood draw volumes and removing both granulocytes and bound drug. Here, we describe a novel protocol whereby CD45 cells are magnetically isolated from human whole blood and co-incubated with serum isolated from the same subject.

Peripheral neuropathy is a complication in systemic sclerosis that is occasionally encountered in clinical settings. The mechanisms underlying this condition remain unclear and treatment strategies have not yet been established, making management challenging. Here, we report a case of peripheral neuropathy associated with systemic sclerosis that was successfully treated with corticosteroid therapy despite the absence of conventional inflammatory findings on histopathology or blood tests.
