Small Extracellular Vesicle (sEV) Uptake from Lung Adenocarcinoma and Squamous Cell Carcinoma Alters T-Cell Cytokine Expression and Modulates Protein Profiles in sEV Biogenesis.

Background: Despite advances in immunotherapy, non-small-cell lung carcinoma (NSCLC)'s clinical success is limited, possibly due to substantial immunological alterations in advanced cancer patients. This study examines the immunomodulatory effects of sEVs derived from lung adenocarcinoma (ADC) and squamous cell carcinoma (SCC) on T cells.

Methods: SEVs were isolated from lung cancer cell lines and Jurkat-E6.

Relationship between autoimmunity and COPD: an investigation based on proteomic profiling and antinuclear antibody screening.

Chronic Obstructive Pulmonary Disease is a major global health concern with significant morbidity and mortality, characterized by heterogeneity influenced by inflammation, oxidative stress, and autoimmunity. This study investigated the role of autoimmunity in stable and exacerbated COPD phenotypes using proteomic and immunological analyses to elucidate molecular mechanisms and identify potential biomarkers. Plasma samples from COPD phenotypes and healthy controls were analyzed using label-free mass spectrometry to identify differentially expressed proteins.

Mesenchymal stem cell-derived exosomes: Characteristics and applications in disease pathology and management.

Mesenchymal stem cells (MSCs) possess a role in tissue regeneration and homeostasis because of inherent immunomodulatory capacity and the production of factors that encourage healing. There is substantial evidence that MSCs' therapeutic efficacy is primarily determined by their paracrine function including in cancers. Extracellular vesicles (EVs) are basic paracrine effectors of MSCs that reside in numerous bodily fluids and cell homogenates and play an important role in bidirectional communication.

Exploring the novel duo of Reticulocalbin, and Sideroflexin as future biomarker candidates for Exacerbated Chronic Obstructive Pulmonary Disease.

Background: COPD is a complex respiratory disorder with high morbidity and mortality rates. Even with the current conventional diagnostic methods, including circulating inflammatory biomarkers, underdiagnosis rates in COPD remain as high as 70%. Our study was a comparative cross-sectional study that aimed to address the diagnostic challenges by identifying future biomarker candidates in COPD variants.

Non-small cell lung carcinoma (NSCLC): Implications on molecular pathology and advances in early diagnostics and therapeutics.

Continuous revision of the histologic and stage-wise classification of lung cancer by the World Health Organization (WHO) provides the foundation for therapeutic advances by promoting molecular targeted and immunotherapies and ensuring accurate diagnosis. Cancer epidemiologic data provide helpful information for cancer prevention, diagnosis, and management, supporting health-care interventions. Global cancer mortality projections from 2016 to 2060 show that cancer will overtake ischemic heart diseases (IHD) as the leading cause of death (18.
