The ‘toxic’ membranes that keep the lungs from becoming inflamed
A study conducted by scientists from the Department of Molecular Medicine, University of Manchester, and the Medical Research Council has shown that the membranes that protect the lungs of mice from developing pulmonary fibrosis and pneumonia are actually highly toxic.
The study, which was published in the Proceedings of the National Academy of Sciences, showed that mice exposed to a single molecule of the membrane’s chemical structure had developed respiratory problems, such as coughing, as well as lung cancer, when exposed to concentrations of 20-50 mg/L (mg/L = 100 µg/L).
The study found that exposure to these levels was comparable to that required for lung cancer in humans.
It’s not clear why the membranes in humans are toxic to the lungs, but the researchers believe it’s because of the chemicals used to produce the membrane.
These compounds are known as ‘chemokines’ and can be found in a variety of substances including tobacco smoke, diesel exhaust, and many other industrial pollutants.
But when it comes to the chemical structure of the ‘chemosynthetic membranes’, these chemicals are extremely stable.
They are known to react with the membrane and form new structures.
“In the human body, it’s known that these chemicals can also be produced in our body through normal physiological processes such as cell division, differentiation, and cell division-independent processes such to the manufacture of proteins,” said Dr Jyoti Prasad, lead author of the study from the Institute for Molecular Medicine and the Institute of Molecular Biology at the University of Sheffield.
“The molecules that are toxic, in this case, are the chemical substances used in the production of the membranes. “
“When we first saw that this compound was the main cause of the respiratory problems that were reported in mice, we were very concerned that this could lead to the creation of a new class of compounds that could affect humans, but this was not the case.” “
The researchers found that the ‘chemical compound’ responsible for the toxicity was the one that was found in cigarette smoke. “

The researchers found that the ‘chemical compound’ responsible for the toxicity was the one that was found in cigarette smoke.
The chemical compound that causes the toxicity in mice is called 1,2-dimethyl-4,5-dimethoxypropane (DPMP), which has a long history of being used in cigarette manufacture.
The team found that DPMP is a component of the chemical membrane, which contains two chemical groups that are known chemically to be stable.
These two chemical compounds are called the chemical groups cationic (c-COOH), which contains an ion, and anionic (A-OH), which does not.
These groups are responsible for forming the chemical ‘cathode’ of the molecular structure that the membrane is made of.
The researchers tested the membranes of mice exposed by inhalation of a small amount of DPMC, and found that mice who were exposed to 10-30 mg/kg of D PMP had significantly higher lung fibrosis rates than those exposed to less than 10 mg/Kg of D P M. The mice who had been exposed to DPMCs concentrations of around 10 mg were also much more susceptible to lung cancer.
The research also showed that the effects of exposure to D PMCs were much more pronounced in mice exposed as infants, and that exposure during pregnancy and lactation were linked to higher risk of lung cancer as well.
“We have known for a while now that lung fibrotation and lung cancer are linked to the use of tobacco smoke as a material for cigarette manufacturing,” Dr Prasud said.
“These are the first results showing that the mechanism responsible for lung fibrophy and lung cancers caused by cigarette smoke may be similar to the mechanisms that lead to lung fibroses and lung fibrous tumours.”
The effects of cigarette smoke exposure are not necessarily related to the presence of the cigarette smoke itself.
However, it has been suggested that smoking is a major factor in lung fibres, and this finding has important implications for future studies on lung fibrogenesis and lung tumours.
“”In this study, we found that there is a correlation between the lung fibre formation, and lung and lung carcinoma formation in mice that were exposed for long periods of time to the DPMPs, and also in mice with lung fibroid disease,” Dr Jyshree Srivastava, who led the study, said.
Dr Prasead added: “Our research has identified a key chemical structure involved in lung disease, and we hope that the findings of our study will lead to a better understanding of the mechanisms involved in tobacco-related lung fibrogroup disease.”
The findings are also important in the field of lung diseases, and have been linked to a range of other factors, such cancer, chronic obstructive pulmonary disease, cardiovascular disease, respiratory diseases
