Results are described of a study of the population and subpopulation composition of lymphocytes in the course of use monochemotherapy (MTS) and polychemotherapy (PCT) in 60 patients with the tumorous form of B-cell chronic lympholeucosis using flow cytometric analysis. It was shown that cytostatic treatment in this form of hemoblastosis results in a reduction of the absolute number of B-lymphocytes due to reduction of general hemocytosis while the relative content of B-cells remained unchanged in MCT and is increased in PCT. A prolonged scheme of PCT is recommended for clinical use that possesses a distinct antitumour effect as compared with MCT and producing a significantly smaller immunosuppressive effect on the T-cell immune system that other schemes of cytostatic therapy.

Purpose: Graves' ophthalmopathy (GO), the most common extrathyroidal manifestation of Graves' disease, is disabling and disfiguring. Recent studies have shown that statins have a protective effect on individuals with GO. Statins were reported to trigger ferroptosis in some disorders, but little is known about whether statins protect against GO via ferroptosis.

P2X7 is an extracellular adenosine 5'-triphosphate (ATP)-gated cation channel that plays various roles in inflammation and immunity. P2X7 is present on peripheral blood monocytes, dendritic cells (DCs), and innate and adaptive lymphocytes. The anti-human P2X7 monoclonal antibody (mAb; clone L4), used for immunolabelling P2X7 or blocking P2X7 activity, is a murine IgG2 antibody, but its ability to mediate complement-dependent cytotoxicity (CDC) is unknown.

Acute lymphoblastic leukaemia is the most common childhood malignancy that remains a leading cause of death in childhood. It may be characterised by multiple known recurrent genetic aberrations that inform prognosis, the most common being hyperdiploidy and t(12;21) . We aimed to assess the applicability of a new imaging flow cytometry methodology that incorporates cell morphology, immunophenotype, and fluorescence in situ hybridisation (FISH) to identify aneuploidy of chromosomes 4 and 21 and the translocation .

Background: Maintenance immunosuppression is required for suppression of alloimmunity or allograft rejection. However, continuous use of immunosuppressants may lead to various side effects, necessitating the use of alternative immunosuppressive drugs. The early secreted antigenic target of 6 kDa (ESAT-6) is a virulence factor and immunoregulatory protein of mycobacterium tuberculosis (Mtb), which alters host immunity through dually regulating development or activation of various immune cells.

Background: The recovery of injured peripheral nerves relies on angiogenesis, where newly formed blood vessels act as pathways guiding Schwann cells across the wound to support axon regeneration. While some research has examined this process, the specific mechanisms of angiogenesis in peripheral nerve healing remain unclear. In vitro models are vital tools to investigate these mechanisms; however, no current in vitro culture methods exist for isolating vascular cells, such as endothelial cells (ECs) and pericytes, specifically from sciatic nerves.
