Internalization and degradation of live Bb within phagosomal compartments of monocytes, macrophages and dendritic cells (DCs), allows for the release of lipoproteins, nucleic acids and other microbial products, triggering a broad and robust inflammatory response. Toll-like receptors (TLRs) are key players in the recognition of spirochetal ligands from whole viable organisms (i.e., vita-PAMPs). Herein we will review the role of endosomal TLRs in the response to the Lyme disease spirochete.

Phagocytosis is a central process by which macrophage cells internalize and eliminate microbes as well as apoptotic cells. The nascent phagosome undergoes a complex maturation process involving sequential fusion with endosomal compartments. The endosomal TLRs, including TLR3, -7, -8, and -9, play a critical role in innate immunity by sensing bacterial or viral nucleic acids and are preferentially transported to the phagosomal membrane of innate immune cells upon activation.

Background: Acute pancreatitis (AP) encompasses a spectrum of pancreatic inflammatory conditions, ranging from mild inflammation to severe pancreatic necrosis and multisystem organ failure. Given the challenges associated with obtaining human pancreatic samples, research on AP predominantly relies on animal models. In this study, we aimed to elucidate the fundamental molecular mechanisms underlying AP using various AP models.

Crohn disease (CD) is an inflammatory bowel disease whose pathogenesis involves inappropriate immune responses toward gut microbiota on genetically predisposed backgrounds. Notably, CD is associated with single-nucleotide polymorphisms affecting several genes involved in macroautophagy/autophagy, the catabolic process that ensures the degradation and recycling of cytosolic components and microorganisms. In a clinical translation perspective, monitoring the autophagic activity of CD patients will require some knowledge on the intrinsic functional status of autophagy.

The Golgi apparatus, long recognized for its roles in protein processing and vesicular trafficking, has recently been identified as a crucial contributor to innate immune signaling pathways. This review discusses our expanding understanding of the Golgi apparatus's involvement in initiating and activating these pathways. It highlights the significance of membrane connections between the Golgi and other organelles, such as the endoplasmic reticulum, mitochondria, endosomes, and autophagosomes.

Article Synopsis
  • * A differential gene expression analysis showed similar immune gene profiles in both male and female sea urchins, with 2721 genes upregulated after exposure to the pathogen Vibrio anguillarum, indicating a robust immune response.
  • * The study identified key immune pathways (like Autophagy and Phagosome) and important receptor families aiding in pathogen recognition, providing valuable insights for the conservation of the P. lividus population.
