Carbon black is a key component of air-borne particulate matter, linked to adverse health outcomes, such as increased susceptibility to respiratory infections and chronic pulmonary disease exacerbations. Fine and ultrafine particles can penetrate the lungs, enter the bloodstream, and induce pathogenetic events. Macrophages play a crucial role in responding to inhaled particles, including carbon black, by initiating an innate immune response and upregulating pro-inflammatory cytokines and anti-oxidative enzymes.

Antigen cross-presentation is the process whereby small peptides derived from exogenous antigens are attached to MHC-I molecules triggering CD8+ T lymphocyte activation. The endocytic route of dendritic cells (DCs) is highly specialised for cross-presentation to initiate cytotoxic immune responses against numerous intracellular pathogens and tumours. In this study, we identify the endosomal protein sorting nexin (SNX) 17 as a key regulator of antigen internalisation and cross-presentation by DCs.

The role of neutrophils in host defense involves several cell processes including phagocytosis, degranulation of antimicrobial proteins, and the release of neutrophil extracellular traps (NETs). In turn, dysregulated cell activity is associated with the pathogenesis of airway and rheumatic diseases, in which neutrophil-derived enzymes including peptidyl-arginine deiminases (PADs) play a role. Known physiological functions of PADs in neutrophils are limited to the activity of PAD isotype 4 in histone citrullination in NET formation.
