Perforin and granzyme B have separate and distinct roles during atherosclerotic plaque development in apolipoprotein E knockout mice. [PDF]

PLoS ONE, 2013
The granzyme B/perforincytotoxic pathway is a well established mechanism of initiating target cell apoptosis. Previous studies have suggested a role for the granzyme B/perforin cytotoxic pathway in vulnerable atherosclerotic plaque formation.

NK cell-derived extracellular granzyme B drives epithelial ulceration during HSV-2 genital infection

Cell Reports, 2023
Summary: Genital herpes is characterized by recurrent episodes of epithelial blistering. The mechanisms causing this pathology are ill defined. Using a mouse model of vaginal herpes simplex virus 2 (HSV-2) infection, we show that interleukin-18 (IL-18 ...

Mucosal-associated invariant T cells in patients with axial spondyloarthritis

Frontiers in Immunology, 2023
BackgroundSeveral studies implicate Th17-cells and its cytokine (IL-17) in disease pathogenesis of spondyloarthritis (SpA), with available evidence supporting a pathogenic role of CD8+ T-cells.

Granzyme A in Chikungunya and Other Arboviral Infections

Frontiers in Immunology, 2020
Granzyme A (GzmA) is secreted by cytotoxic lymphocytes and has traditionally been viewed as a mediator of cell death. However, a growing body of data suggests the physiological role of GzmA is promotion of inflammation.

Granzyme A Is Expressed in Mouse Lungs during Mycobacterium tuberculosis Infection but Does Not Contribute to Protection In Vivo. [PDF]

PLoS ONE, 2016
Granzyme A, a serine protease expressed in the granules of cytotoxic T and Natural Killer cells, is involved in the generation of pro-inflammatory cytokines by macrophages. Granzyme A has been described to induce in macrophages in vitro the activation of

Fish Granzyme A Shows a Greater Role Than Granzyme B in Fish Innate Cell-Mediated Cytotoxicity

Frontiers in Immunology, 2019
Granzymes (Gzm) are serine proteases, contained into the secretory granules of cytotoxic cells, responsible for the cell-mediated cytotoxicity (CMC) against tumor cells and intracellular pathogens such as virus and bacteria.

Contact-Dependent Granzyme B-Mediated Cytotoxicity of Th17-Polarized Cells Toward Human Oligodendrocytes

Frontiers in Immunology, 2022
Multiple sclerosis (MS) is characterized by the loss of myelin and of myelin-producing oligodendrocytes (OLs) in the central nervous system (CNS). Pro-inflammatory CD4+ Th17 cells are considered pathogenic in MS and are harmful to OLs.

Study of serum Granzyme B in heavy cigarette smokers with and without chronic obstructive pulmonary disease

Egyptian Journal of Chest Disease and Tuberculosis, 2014
Background: Inflammation of the airways is present in COPD with increased number of inflammatory cells including killer cells that lyse their target cells by two mechanisms; membranolysis in which secreted molecules such as granzymes form pores in the ...

Study of effect of inhaled versus oral corticosteroids on sputum granzyme B in patients with moderate persistent bronchial asthma

Egyptian Journal of Chest Disease and Tuberculosis, 2015
Background: Asthma is a major public health problem with a high economic burden. It involves several inflammatory cells and multiple mediators. Granzyme B is an inflammatory mediator expressed and secreted by both immune and non immune cells. Recently it
