J Invertebr Pathol 2024; 207:108214. [PMID: 39366479 DOI: 10.1016/j.jip.2024.108214] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/27/2024] [Revised: 09/08/2024] [Accepted: 10/01/2024] [Indexed: 10/06/2024]
Abstract
Beauveria bassiana (B. bassiana) is a common fungal disease in sericulture. Previous research has primarily focused on investigating genes involved in innate immunity. However, the response of Bombyx mori (B. mori) to B. bassiana requires the coordination of other biological processes in addition to the immune system. We measured protein expression profile of B. mori after inoculating B. bassiana using iTRAQ technology in previous. Here we constructed a co-expression protein-protein interaction network of B. mori in response to B. bassiana infection. Subnetworks and modules were analyzed, and the functions of these modules were annotated. The results revealed the identification of numerous proteins associated with cellular immunity, including those involved in phagosomes, lysosomes, mTOR signaling, sugar metabolism, and the ubiquitin-proteasome pathway. Meanwhile, we observed that the pathways involved in protein synthesis were activated, including pyruvate and purine metabolism, RNA transport, ribosome, protein processing in endoplasmic reticulum, and protein export pathways, during B. bassiana infection. Based on this analysis, we selected six candidate genes (shock protein, ribosome, translocon, actin muscle-type A2, peptidoglycan recognition protein, and collagenase) that were found to be related to the response to B. bassiana. Further verification experiments demonstrated significant changes in their expression levels after inoculation with B. bassiana. These research findings provide new insights into the molecular mechanism of insect immune response to fungal infection.

Abstract
HSV can evade host defenses and cause lifelong infection and severe illness. Lysosomes are catabolic organelles that play an important role in the regulation of cellular homeostasis. Lysosomal dysfunction and alterations in the process of autophagy have been identified in a variety of diseases, including HSV infection, and targeting lysosomes is a potential anti-HSV therapeutic strategy. This article reviews the role of lysosomes and lysosome-associated proteins in HSV infection, providing attractive targets and novel strategies for the treatment of HSV infection.

Abstract
The recent novel coronavirus (SARS-CoV-2) disease (COVID-19) outbreak created a severe public health burden worldwide. Unfortunately, the SARS-CoV-2 variant is still spreading at an unprecedented speed in many countries and regions. There is still a lack of effective treatment for moderate and severe COVID-19 patients, due to a lack of understanding of the SARS-CoV-2 life cycle. Lysosomes, which act as “garbage disposals” for nearly all types of eukaryotic cells, were shown in numerous studies to support SARS-CoV-2 replication. Lysosome-associated pathways are required for virus entry and exit during replication. In this review, we summarize experimental evidence demonstrating a correlation between lysosomal function and SARS-CoV-2 replication, and the development of lysosomal perturbation drugs as anti-SARS-CoV-2 agents.

Abstract
Lysosomes are the main degradative organelles of almost all eukaryotic cells. They fulfil a crucial function in cellular homeostasis, and impairments in lysosomal function are connected to a continuously increasing number of pathological conditions. In recent years, lysosomes are furthermore emerging as control centers of cellular metabolism, and major regulators of cellular signaling were shown to be activated at the lysosomal surface. To date, >300 proteins were demonstrated to be located in/at the lysosome, and the lysosomal proteome and interactome is constantly growing. For the identification of these proteins, and their involvement in cellular mechanisms or disease progression, mass spectrometry (MS)-based proteomics has proven its worth in a large number of studies. In this review, we are recapitulating the application of MS-based approaches for the investigation of the lysosomal proteome, and their application to a diverse set of research questions. Numerous strategies were applied for the enrichment of lysosomes or lysosomal proteins and their identification by MS-based methods. This allowed for the characterization of the lysosomal proteome, the investigation of lysosome-related disorders, the utilization of lysosomal proteins as biomarkers for diseases, and the characterization of lysosome-related cellular mechanisms. While these >60 studies provide a comprehensive picture of the lysosomal proteome across several model organisms and pathological conditions, various proteomics approaches have not been applied to lysosomes yet, and a large number of questions are still left unanswered.

Abstract
Lysosomes are involved in pathogenesis of a variety of neurodegenerative diseases and play a large role in neurodegenerative disorders caused by virus infection. However, whether virus-infected cells or animals can be used as experimental models of neurodegeneration in humans based on virus-related lysosomal dysfunction remain unclear. Porcine hemagglutinating encephalomyelitis virus displays neurotropism in mice, and neural cells are its targets for viral progression. PHEV infection was confirmed to be a risk factor for neurodegenerative diseases in the present. The findings demonstrated for the first time that PHEV infection can lead to lysosome disorders and showed that the specific mechanism of lysosome dysfunction is related to PGRN expression deficiency and indicated similar pathogenesis compared with human neurodegenerative diseases upon PHEV infection. Trehalose can also increase progranulin expression and rescue abnormalities in lysosomal structure in PHEV-infected cells. In conclusion, these results suggest that PHEV probably serve as a disease model for studying the pathogenic mechanisms and prevention of other degenerative diseases.

Abstract
Cotton bollworm (Helicoverpa armigera) is the major insect herbivore of cotton plants. As its larvae feed and grow on cotton, H. armigera can likely tolerate gossypol, the main defense metabolite produced by cotton plants, through detoxification and sequestration mechanisms. Recent reports have shown that various P450 monooxygenases and UDP-glycosyltransferases in H. armigera are involved in gossypol detoxification, while the roles of ABC transporters, another gene family widely associated with metabolite detoxification, remain to be elucidated. Here, we show that ingestion of gossypol-infused artificial diet and cotton leaves significantly induced the expression of HaABCB6 in H. armigera larvae. Knockdown and knockout of HaABCB6 increased sensitivity of H. armigera larvae to gossypol. Moreover, HaABCB6-GFP fusion protein was localized on lysosomes in Hi5 cells and its overexpression significantly enhanced gossypol tolerance in vitro. These experimental results strongly support that HaABCB6 plays an important role in gossypol detoxification by H. armigera.

Abstract
2-Nonenal is a long-chain aliphatic aldehyde containing nine carbons and an unsaturated bond. 2-Nonenal is the primary cause of odor associated with aging, with an unpleasant greasy and grassy odor. Lysosome, mitochondria, and peroxisome are significant organelles in eukaryotic cells that contain various hydrolases that degrade biomolecules. Proteins in mitochondria and peroxisome also contain aldehyde dehydrogenase. We performed trans-2-nonenal treatment using lysosomal-related enzymes extracted from hen egg white (HEW). As trans-2-nonenal is more structurally stable than cis-2-nonenal, it was selected as the target aldehyde. HEW contains various biologically active proteins and materials such as albumin, ovotransferrin, lysosome, peroxisome, and mitochondria. Here, complementary experiments were conducted to evaluate the role of lysosomal-related enzymes in the treatment of trans-2-nonenal. The activity of lysosomal-related enzymes was confirmed via antimicrobial test against E. coli. HPLC analysis was used to determine the reduction of trans-2-nonenal. The trans-2-nonenal treatment depended on the reaction time and enzyme concentration. Materials considered as an intermediate from trans-2-nonenal treatment were detected by GC/MS spectrometer. Under acidic conditions (pH 6), lysosomal-related enzymes were the most efficient in the treatment of trans-2-nonenal. Furthermore, based on differential pH testing, we found the conditions under which all the 50 ppm trans-2-nonenal was removed. Therefore, our results suggest that the lysosomal-related enzymes reduced trans-2-nonenal, suggesting clinical application as anti-aging deodorants.

Abstract
At present, the lysosome pathway (LP) and proteasome pathway (PP) are known as major clearance systems in eukaryotic cells. The laticifer, a secretory tissue, degrades some cytoplasm during development. In this study, we investigated the distribution of LP and PP in non-articulated laticifers of Euphorbia helioscopia L. Electron microscopy revealed that, plastids, mitochondria and some cyotsol were degraded in the late development laticifers, where there were numerous vesicles originated from dicytosomes. Accordingly, some key proteins in LP and PP were detected in E. helioscopia latex using isobaric tags for relative and absolute quantitation (iTRAQ) proteomics. Further immunohistochemistry analysis revealed that the clathrin heavy chain (CHC) belonging to LP and the ubiquitin-mediated proteasome degradation increases gradually as the laticifer develops. Immuno-electron microscopy revealed that the cysteine protease, CHC and AP-2 complex subunit beta-1 belonging to LP were mainly distributed in vesicles deriving from dicytosomes, which we called lysosome-like vesicles. Ubiquitin was widely distributed in the cytosol, and proteasome activity was significantly reduced when various concentrations of the inhibitor MG132 were added to the latex total protein. We hypothesize that LP and PP are distributed in E. helioscopia laticifers; and it was speculated that LP and PP might be involved in the degradation of organelles and some cytoplasmic matrix in E. helioscopia laticifers.

Abstract
The mudflat crab Helice tientsinensis is one of the most economically important aquaculture species in China. Nevertheless, it is susceptible to various diseases caused by viruses, bacteria and rickettsia-like organisms. A better understanding of the immune system and genes related to the responses to bacterial and viral infection is required. Herein, the hepatopancreas transcriptome of H. tientsinensis was analyzed by comparing control and lipopolysaccharide (LPS)-stimulated RNA-Seq data, yielding 91,885,038 bp and 13.78 Gb of clean reads. Following assembly and annotation, 93,207 unigenes with an average length of 883 bp were identified, of which 31,674 and 13,700 were annotated in Gene Ontology (GO) and Kyoto Encyclopedia of Genes and Genomes (KEGG) databases, respectively. Following LPS, 4845 differentially expressed genes (DEGs) were identified, of which 2491 and 2354 were up- and down-regulated, respectively. To further investigate immune-related DEGs, KEGG enrichment analysis identified immune response pathways, most notably the peroxisome and Toll-like receptor signaling pathways. Quantitative real time-PCR (qRT-PCR) confirmed the up-regulation of a random selection of DEGs. This systematic transcriptomic analysis of the innate immune pathway in H. tientsinensis expands our understanding of the immune system in crabs.

STAT3 associates with vacuolar H +-ATPase and regulates cytosolic and lysosomal pH. Cell Res 2018; 28:996-1012.

Abstract
Dysregulated intracellular pH is emerging as a hallmark of cancer. In spite of their acidic environment and increased acid production, cancer cells maintain alkaline intracellular pH that promotes cancer progression by inhibiting apoptosis and increasing glycolysis, cell growth, migration, and invasion. Here we identify signal transducer and activator of transcription-3 (STAT3) as a key factor in the preservation of alkaline cytosol. STAT3 associates with the vacuolar H+-ATPase in a coiled-coil domain-dependent manner and increases its activity in living cells and in vitro. Accordingly, STAT3 depletion disrupts intracellular proton equilibrium by decreasing cytosolic pH and increasing lysosomal pH, respectively. This dysregulation can be reverted by reconstitution with wild-type STAT3 or STAT3 mutants unable to activate target genes (Tyr705Phe and DNA-binding mutant) or to regulate mitochondrial respiration (Ser727Ala). Upon cytosolic acidification, STAT3 is transcriptionally inactivated and further recruited to lysosomal membranes to reestablish intracellular proton equilibrium. These data reveal STAT3 as a regulator of intracellular pH and, vice versa, intracellular pH as a regulator of STAT3 localization and activity.

Abstract
Different liver cell types are endowed with immunological properties, including cell-intrinsic innate immune functions that are important to initially control pathogen infections. However, a full landscape of expression and functionality of the innate immune signaling pathways in the major human liver cells is still missing. In order to comparatively characterize these pathways, we purified primary human hepatocytes, hepatic stellate cells, liver sinusoidal endothelial cells (LSEC), and Kupffer cells (KC) from human liver resections. We assessed mRNA and protein expression level of the major innate immune sensors, as well as checkpoint-inhibitor ligands in the purified cells, and found Toll-like receptors (TLR), RIG-I-like receptors, as well as several DNA cytosolic sensors to be expressed in the liver microenvironment. Amongst the cells tested, KC were shown to be most broadly active upon stimulation with PRR ligands emphasizing their predominant role in innate immune sensing the liver microenvironment. By KC immortalization, we generated a cell line that retained higher innate immune functionality as compared to THP1 cells, which are routinely used to study monocyte/macrophages functions. Our findings and the establishment of the KC line will help to understand immune mechanisms behind antiviral effects of TLR agonists or checkpoint inhibitors, which are in current preclinical or clinical development.

Abstract
Bacterial pathogens use various strategies to interfere with host cell functions. Among these strategies, bacteria modulate host gene transcription, thereby modifying the set of proteins synthetized by the infected cell. Bacteria can also target pre-existing host proteins and modulate their post-translational modifications or trigger their degradation. Analysis of protein levels variations in host cells during infection allows to integrate both transcriptional and post-transcriptional regulations induced by pathogens. Here, we focused on host proteome alterations induced by the toxin Listeriolysin O (LLO), secreted by the bacterial pathogen Listeria monocytogenes. We showed that a short-term treatment with LLO remodels the host cell proteome by specifically decreasing the abundance of 149 proteins. The same decrease in host protein levels was observed in different epithelial cell lines but not in macrophages. We show in particular that this proteome remodeling affects several ubiquitin and ubiquitin-like ligases and that LLO leads to major changes in the host ubiquitylome. Strikingly, this toxin-induced proteome remodeling involves only post-transcriptional regulations, as no modification in the transcription levels of the corresponding genes was observed. In addition, we could show that Perfringolysin O, another bacterial pore-forming toxin similar to LLO, also induces host proteome changes. Taken together, our data reveal that different bacterial pore-forming toxins induce important host proteome remodeling, that may impair epithelial cell functions.
