Quoted from [1], "The factors regulating cytokine release within adipose tissue appear to include usual ‘inflammatory‘ stimuli such as lipopolysaccaride, but also the size of the fat cells per se and catecholamines."
所以話,「發炎」亦可以指呢啲factors會導致嘅downstream effects,就算冇irritant都可以發生,更準確嘅definition可能係「an event orchestrated by inflammatory cytokines & cells of the immune system, that has several characteristic hallmarks such as 紅腫熱痛 & loss of function」?
