Pyrethroids are popular insecticides. Shortness of breath and dyspnea key signs exposure; however, their respiratory effects rarely studied. This study investigated the combination ratios specific blood tests lung lesions as cypermethrin (CY) in rabbits. The CY at various doses times novelty this study. Doses (50, 100, 150 mg.kg-1 body weight) were injected intraperitoneally every week for up to 9 weeks rabbits assigned into four equal groups. Data analysis revealed signs, significantly (p ≤ 0.05) lower fibrinogen, higher neutrophils-lymphocytes (NL), LDH-lymphocytes (LL), De-Ritis (DR), lungs. frequency incidence these dose dosage dependent. leads pulmonary allergic effects. Lung injury increases cell-free heme plasma, causing edema with hemolysis. Emphysema fibrosis followed migration basophils mononuclear cells inferred that exposure caused NL, LL, DR ratios, lesions, which forecast poor immunity, especially increased risk cardiac diseases.

Lipid nanoparticles (LNPs) have emerged as a powerful non-viral carrier for drug delivery. With the prevalence of respiratory diseases, particularly highlighted by current COVID-19 pandemic, investigations into applying LNPs to deliver inhaled therapeutics directly lungs are underway. The progress in LNP development well recent pre-clinical studies three main classes encapsulated drugs: small molecules, nucleic acids and proteins/peptides will be discussed. advantages pulmonary delivery system such reducing systemic toxicity enabling higher local concentration evaluated together with challenges design considerations improved formulations. This review provides perspective on future prospects LNP-mediated diseases.

Lung macrophages (Mφs) are essential for pulmonary innate immunity and host defense due to their dynamic polarization phenotype shifts. Mesenchymal stromal cells (MSCs) have secretory, immunomodulatory, tissue-reparative properties shown promise in acute chronic inflammatory lung diseases COVID-19. Many beneficial effects of MSCs mediated through interaction with resident alveolar interstitial Mφs. Bidirectional MSC-Mφ communication is achieved direct contact, soluble factor secretion/activation, organelle transfer. The microenvironment facilitates MSC secretion factors that result Mφ towards an immunosuppressive M2-like the restoration tissue homeostasis. turn can affect immune regulatory function engraftment reparatory effects. This review article highlights mechanisms crosstalk between Mφs potential role repair diseases.

Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) that causes disease 19 (COVID-19) has numerous risk factors leading to severe with high mortality rate. Oxidative stress excessive production of reactive oxygen species (ROS) lower glutathione (GSH) levels seems be a common pathway associated the COVID-19 mortality. GSH is unique small but powerful molecule paramount for life. It sustains adequate redox cell signaling since physiologic level oxidative fundamental controlling life processes via signaling, oxidation and tissue damage.

The pathogenetic mechanism of post-Covid-19 pulmonary fibrosis is currently a topic intense research interest, but still largely unexplored. aim this work was to carry out systematic exploratory search the literature (Scoping review) identify and systematize main mechanisms that are believed be involved in phenomenon, order highlight same molecular aspect lung. These aims could essential future for therapeutic management. We identified all primary studies involving post COVID19 syndrome with as endpoint by performing data searches various review databases. Two reviewers independently reviewed abstracts (398) full text data. quality study has been assess through SANRA protocol. A total 32 were included, included possible involvement inflammatory cytokines, concerned renin-angiotensin system, potential role galectin-3, epithelial injuries fibrosis, alveolar type 2 involvement, Neutrophil extracellular traps (NETs) others implied other specific aspects (relationship clinical mechanical factors, transition mesenchymal, TGF-β signaling pathway, midkine, caspase macrophages, genetics). In most cases, these narrative reviews or letters editor, except 10 articles, which presented original data, albeit sometimes experimental models. From development researches, progress knowledge phenomenon hopefully its prevention therapy may originate.

Pulmonary alveolar proteinosis (PAP) is a rare pulmonary disorder that characterized by the abnormal accumulation of surfactant within alveoli. Alveolar macrophages (AMs) have been identified as playing pivotal role in pathogenesis PAP. In most PAP cases, disease triggered impaired cholesterol clearance AMs depend on granulocyte-macrophage colony-stimulating factor (GM-CSF), resulting defective and disruption homeostasis. Currently, novel pathogenesis-based therapies are being developed target GM-CSF signaling, homeostasis, immune modulation AMs. this review, we summarize origin functional PAP, well latest therapeutic strategies aimed at addressing disease. Our goal to provide new perspectives insights into thereby identify promising treatments for

Abstract Background Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), with different antigenic variants, has posed a significant threat to public health. It is urgent develop inhalable vaccines, instead of injectable elicit mucosal immunity against viral infections. Methods We reported an hybrid nanovaccine (NV RBD -MLipo) boost protective SARS-CoV-2 infection. Nanovesicles derived from genetically engineered 293T cells expressing ) were fused pulmonary surfactant (PS)-biomimetic liposomes containing MPLA (MLipo) yield NV -MLipo, which possessed virus-biomimetic structure, inherited expression and versatile properties. Results In contrast subcutaneous vaccination, via could efficiently enter the alveolar macrophages (AMs) AMs activation through MPLA-activated TLR4/NF-κB signaling pathway. Moreover, -MLipo induced T B activation, high level RBD-specific IgG secretory IgA (sIgA), thus elevating systemic immune responses, while reducing side effects. also demonstrated broad-spectrum neutralization activity (WT, Delta, Omicron) pseudovirus, protected immunized mice WT pseudovirus Conclusions This as effective safe nanovaccine, holds huge potential provoke robust immunity, might be promising vaccine candidate combat infectious diseases, including COVID-19 influenza.
