Witryna1 gru 2024 · Legionella takes control of host membranes. Some intracellular bacteria, such as Legionella pneumophila, inhabit membrane-bound compartments inside host cells (1). Once there, the microbes typically interact with host membranes and secrete so-called effector proteins that help the microbes wield control over them (2). WitrynaThe interferon-γ (IFNγ)/interleukin-12 (IL-12) axis is crucial to host defense against intracellular pathogens, including mycobacteria, Listeria, and Salmonella species. Dendritic cells and macrophages produce interleukin-12 in response to bacterial pathogens that in turn stimulate the secretion of IFNγ by T cells and natural killer cells.
Witryna8 mar 2024 · This review discusses how intracellular bacteria are detected by inflammasomes, how the specific sensing mechanism of eachinflammasome receptor restricts the ability of bacteria to evade immune recognition, and how host cell death is used to control bacterial replication in vivo.
