Cellular Defences of the Lung: Comparative Perspectives

Destroyed lung complicated with empyema

Case report 76 year old woman who went to her local hospital with fever up to 39°C, brownish expectoration, left chest pain and breathlessness that has been increasing in recent weeks. She had a colostomy as a result of an adenocarcinoma colon intervention 18 years ago. She used wheelchair due to an ischemic stroke with paresis of the left lower limb during the postoperative. She had never smok...

Priming of indirect defences.

Leaf damage induces in many plant species the secretion of extrafloral nectar (EFN) and/or the release of specific odours (volatile organic compounds, VOCs). Both traits attract carnivorous arthropods and function as indirect plant defences by increasing the predation pressure on attacking herbivores. We have conducted field experiments in Mexico and found that plants that had been exposed to V...

Lung defences: an overview

Lung defences are dependant on a complex array of mechanisms in the upper airways, which must to be differentiated from those of the distal airways. However, the first lines of defence in the proximal and distal airways are predominantly based on mechanical barriers and several mechanisms related to innate immunity. If pathogens or antigens reach the interstitium, dendritic cells will take up t...

Ultrastructure of fish cells involved in cellular defences against Saprolegnia infections: evidence of non-leucocytic nature.

Fish cells attached to hyphae were observed in brown trout Salmo trutta L. infected with Saprolegnia parasitica. Earlier studies with light microscopy indicated that these cells were lymphocytes and neutrophils and that they were involved in the defence mechanisms against Saprolegnia infections. However, using electron microscopy, we found these attached cells did not show leucocytic characteri...
