Alternatively activated macrophages do not synthesize catecholamines or contribute to adipose tissue adaptive thermogenesis

Nature Medicine, 2017
Adaptive thermogenesis is the process of heat generation in response to cold stimulation. It is under the control of the sympathetic nervous system, whose chief effector is the catecholamine norepinephrine (NE).

Torpor‐assisted migration: Regular use of shallow torpor reduces rest‐phase energy expenditure for songbirds during migration

Journal of Animal Ecology, EarlyView.
Migrating songbirds regularly use shallow torpor (up to 98% of birds for some species) to save energy (up to 42%) during inactive periods. This Ruby‐crowned Kinglet Corthylio calendula that was captured after a spring snowstorm highlights the value of being able to save energy when encountering unfavourable conditions.

Infrared thermography unveiled the variation of brown adipose tissue thermogenesis among East Asian adults

Physiological Reports
The thermogenesis of brown adipose tissue (BAT) is interesting because the contribution to human adaptation to cold and obesity resistance has been suggested.

Acyl CoA-binding protein in brown adipose tissue acts as a negative regulator of adaptive thermogenesis

Molecular Metabolism
Objective: Defective activity of brown adipose tissue (BAT) is linked to obesity and cardiometabolic diseases. While much is known regarding the biological signals that trigger BAT thermogenesis, relatively little is known about the repressors that may ...

γδT cells and adipocyte IL-17RC control fat innervation and thermogenesis

Nature, 2019
The sympathetic nervous system innervates peripheral organs to regulate their function and maintain homeostasis, whereas target cells also produce neurotrophic factors to promote sympathetic innervation 1 , 2 .

Can Fecal T3 Metabolite Level Fluctuations in European Roe Deer (Capreolus capreolus) Give Insights on Body Condition and Thermal Stress?

Integrative Zoology, EarlyView.
European roe deer fecal samples were assayed to investigate the potential fluctuations of fecal thyroid hormone metabolites (FTMs) in response to environmental (e.g., the temperature, local densities) and individual (e.g., sex, age, body, and nutritional conditions) variables.

Absence of MCJ/DnaJC15 promotes brown adipose tissue thermogenesis

Nature Communications
Obesity poses a global health challenge, demanding a deeper understanding of adipose tissue (AT) and its mitochondria. This study describes the role of the mitochondrial protein Methylation-controlled J protein (MCJ/DnaJC15) in orchestrating brown ...

Orexin modulates brown adipose tissue thermogenesis

Biomolecular Concepts, 2012
Non-shivering thermogenesis in brown adipose tissue (BAT) plays an important role in thermoregulation. In addition, activations of BAT have important implications for energy homeostasis due to the metabolic consumption of energy reserves entailed in the ...

Ecophysiology of an Avian Invader: Body Condition and Metabolic Rate Adjustments to Ambient Temperature

Integrative Zoology, EarlyView.
This study examines the ecophysiological responses of common waxbills to temperature variation in Portugal. We measured body condition and basal metabolic rate (BMR) during summer and winter across two regions in Portugal. Body condition was negatively correlated with temperature, while the relationship between BMR and temperature varied seasonally. In

Effect of altered gravity on temperature regulation in mammals: Investigation of gravity effect on temperature regulation in mammals [PDF]

Male, Long-Evans hooded rats were instrumented for monitoring core and hypothalamic temperatures as well as shivering and nonshivering thermogenesis in response to decreased ambient temperature in order to characterize the nature of the neural controller
