inflammation, neurodegeneration and bacterial/viral infection are primarily diseases of cells. Without a molecular understanding of the underlying cell biology, intelligent directed therapeutic intervention is impossible.
Flu vaccines delivered using microneedles that dissolve in the skin can protect people against infection even better than the standard needle-delivered vaccine,

Skin adipocytes help protect against infections Richard Gallo MD Phd professor and chief of dermatology at UC San diego School of medicine and colleagues have uncovered a previously unknown role for dermal fat cells known as adipocytes:
The human body's defense against microbial infection is tiered complex multi and involves numerous cell types culminating in the arrival of neutrophils
and leukocytes residing in the area of infection. Staphylococcus aureus is a common bacterium and major cause of skin and soft tissue infections in humans.
The emergence of antibiotic-resistant forms of S. aureus is a significant problem worldwide in clinical medicine.
if the subcutaneous fat played a role in preventing skin infections. Ling Zhang Phd the first author of the paper exposed mice to S. aureus and within hours detected a major increase in both the number and size of fat cells at the site of infection.
More importantly these fat cells produced high levels of an antimicrobial peptide (AMP) called cathelicidin antimicrobial peptide or CAMP.
AMPS are our natural first line defense against infection. They are evolutionarily ancient and used by all living organisms to protect themselves said Gallo.
Too little CAMP and people experience frequent infections. The best example is atopic eczema (a type of recurring itchy skin disorder.
These patients can experience frequent Staph and viral infections. But too much CAMP is also bad.
The scientists confirmed their findings by analyzing S. aureus infections in mice unable to either effectively produce adipocytes or

They discovered a novel link between food intake during the early stages of infection and the outcome of the disease, identifying two molecular pathways that could serve as new targets for treatment."
