This study investigates whether allergen exposure elevates the risk of diabetes or cardiovascular diseases using acute OVA (Ovalbumin) allergen exposure model. We hypothesize that exposure to allergen can induce adipose tissue inflammation and affect adiponectin levels. An intranasal challenge with OVA male C57BL/6 mice was performed at dose of 6.25, 12.5, 25, 50 and 100. μg, and compared to which challenge with PBS (phosphate buffered saline). Results showed that acute OVA exposure did not only cause airway inflammation in study mice, but also decreased serum adiponectin levels with a dose-response effect. When examining the gonadal adipose tissues, there was no significantly difference of adiponectin mRNA in OVA challenged mice compared to those PBS challenged, but lower inguinal adiponectin mRNA expression was found compared to those PBS-challenged, and had a good relationship with the serum adiponectin. Inguinal adipose tissues of OVA challenged mice, had significantly lower adipose tissue weight, and higher TNF-α expression without statistical significance. Our data indicate that acute OVA exposure appears to affect the characteristics of adipose tissues, and change the adiponectin levels in serum and adipose tissues. Allergen exposure may be considered a potential risk factor for presenting diabetes or cardiovascular diseases.
