Engineered nanoparticles (ENPs) are produced and used in increasing quantities for industrial products, food, and drugs. The fate of ENPs after usage and impact on health is less known. Especially as air pollution, suspended nanoparticles have raised some attention, causing diseases of the lung and cardiovascular system.

To date, it is not known which genes specifically instruct these precursor cells to elaborate cotyledons, nor is the role of auxin in cotyledon development clear. In laterne mutants, the cotyledons are precisely deleted, yet the hypocotyl and root are unaffected.

- Recent studies show that high levels of particulate air pollution (PM) are linked to increased heart and lung diseases, impacting overall health and mortality.
- Mechanisms by which PM affects cardiovascular health include inflammation, dysfunction in the nervous system, and problems in heart muscle, but understanding of these processes is still incomplete.
- More research is needed to clarify how PM exposure leads to adverse cardiovascular effects and to establish clearer biological links.
Background: Air pollution episodes are strongly associated with increased cardiovascular morbidity and mortality. The effect of ultrafine particles (UFPs), when translocated after inhalation, on the microcirculation of extrapulmonary organs remains unclear.
Methods And Results: In C57BL/6 mice, either carbon black UFPs (1x10(7) and 5x10(7)) or vehicle was infused intra-arterially.
