Resumen

The development of obesity may be aggravated if obesity itself insulates against heat loss and thus diminishes the amount of food burnt for body temperature control. This would be particularly important under normal laboratory conditions where mice experience a chronic cold stress (at ≈20°C). We used Scholander plots (energy expenditure plotted against ambient temperature) to examine the insulation (thermal conductance) of mice, defined as the inverse of the slope of the Scholander curve at subthermoneutral temperatures. We verified the method by demonstrating that shaved mice possessed only h

Resumen

The purpose of these experiments was to test the hypothesis that gut flora influences the body temperature of rodents. Rats and mice were implanted with biotelemetry transmitters that enabled us to record both abdominal temperature and activity for long periods of time. Rats given nonabsorbable antibiotics in their drinking water, which reduced their gut flora, had a marked decrease in both their daytime and nighttime temperatures. Similar results were found with germfree mice. The circadian rhythms in body temperature of germfree and conventionalized mice were not different. However, the body

Resumen

Breathing pattern is influenced by body temperature. However, the central mechanism for changing breathing patterns is unknown. Central histamine is involved in heat loss mechanisms in behavioral studies, but little is known about its effect on breathing patterns. We examined first the effect of body temperature on breathing patterns with increasing hypercapnia in conscious mice and then that of the depletion of central histamine by S(+)-α-fluoromethylhistidine hydrochloride (α-FMH) (100 mg/kg ip), a specific inhibitor of histidine decarboxylase, at normal and raised body temperatures.

Resumen

We have studied, using a telemetry system, the pyrogenic properties of recombinant murine interleukin-18 (rmIL-18) injected into the peritoneum of C57BL/6 mice. The effect of IL-18 was compared with the febrile response induced by human IL-1β, lipopolysaccharide (LPS), and recombinant murine interferon-γ (rmIFN-γ). Both IL-1β and LPS induced a febrile response within the first hour after the intraperitoneal injection, whereas rmIL-18 (10–200 μg/kg) and rmIFN-γ (10–150 μg/kg) did not cause significant changes in the core body temperature of mice.

Abstract Temperature affects body physiological functions, including immunity in ways that influence survival. This study investigated the effect of temperature on macrophage activation and metabolism across species. Macrophages were isolated from mice, chicken or rainbow trout primary tissue or from macrophage cell lines and were activated with lipopolysaccharide (LPS) or IFN-γ. For mice, both Raw264.7 and primary cells, nitric oxide (NO) production was similar at 35°C and 37°C but dropped dramatically at temperatures below 35°C.

Resumen

One major factor affecting physiology often overlooked when comparing data from animal models and humans is the effect of ambient temperature. The majority of rodent housing is maintained at ~22°C, the thermoneutral temperature for lightly clothed humans. However, mice have a much higher thermoneutral temperature of ~30°C, consequently data collected at 22°C in mice could be influenced by animals being exposed to a chronic cold stress. The aim of this study was to investigate the effect of housing temperature on glucose homeostasis and energy metabolism of mice fed normal chow or a high-fat, o

Resumen

Dietary dehydroepiandrosterone (DHEA) reduces food intake in mice, and this response is under genetic control. Moreover, both food restriction and DHEA can prevent or ameliorate certain diseases and mediate other biological effects. Mice fed DHEA (0.45% w/w of food) and mice pair-fed to these mice (food restricted) for 8 weeks were tested for changes in body temperature. DHEA was more efficient than food restriction alone in causing hypothermia. DHEA injected intraperitoneally also induced hypothermia that reached a nadir at 1 to 2 hr, and slowly recovered by 20 to 24 hr. This effect was dose

Abstract Mice used for modeling cancer and anti-tumor immunity experience increased adrenergic stress due to IACUC-mandated cool housing temperatures.

An earlier study showed that the presence of gut flora elevates body temperature of mice and rats. In these experiments, we questioned whether the signal coming from the gut was endotoxin from gram-negative (Gm-) bacteria or some signal derived from gram-positive (Gm+) microorganisms. To test the idea that endotoxin is responsible for the effects of flora, we compared the temperature of the endotoxin-resistant mouse (C3H/HeJ) with that of endotoxin-sensitive strains of mice (C3H/SnJ and C3H/HeN). Temperature of C3H/HeJ was not different from that of C3H/SnJ or C3H/HeN during the light period b

Ambient air temperatures (Ta) of <6°C or >29°C have been shown to induce large changes in arterial blood pressure and heart rate in homeotherms. The present study was designed to investigate whether small incremental changes in Ta, such as those found in typical laboratory settings, would have an impact on blood pressure and other cardiovascular parameters in mice and rats. We predicted that small decreases in Ta would impact the cardiovascular parameters of mice more than rats due to the increased thermogenic demands resulting from a greater surface area-to-volume ratio in mice relative

Recent studies using reptiles and other ectothermic species have shown that hypoxia lowers the set point for the control of body temperature. This is characterized by a preference for cooler ambient (Ta) and deep body temperatures (Tb) when placed in a temperature gradient.

Resumen

Environmental temperature remarkably impacts on metabolic homeostasis, raising a serious concern about the optimum housing temperature for translational studies. Recent studies suggested that mice should be housed slightly below their thermoneutral temperature (26°C). On the other hand, the external temperature, also known as a zeitgeber, can reset the circadian rhythm. However, whether housing temperature affects the circadian oscillators of the liver remains unknown. Therefore, we have compared the effect of two housing temperatures, namely 21°C (conventional; TC) and 26°C (thermoneutral; TN

Abstract Recently it was reported that maintenance of mice at thermoneutral temperatures (TT, the temperature at which basal metabolism is sufficient to maintain body temperature, 30oC) enhanced antitumor immune responses and reduced tumor growth, relative to standard vivarium temperatures (ST, 22oC). We hypothesized that mice maintained at ST may have impaired production of T cell chemoattractant cytokines and subsequent T cell infiltration. In mice bearing breast tumors or solid or metastatic-like melanomas, intratumoral expression of CXCL9 and CXCL10 (CXCR3-cognate chemokines) was enhanced

Resumen

ABSTRACT The present work calculated the rate of inactivation of Cryptosporidium parvum oocysts attributable to daily oscillations of low ambient temperatures. The relationship between air temperature and the internal temperature of bovine feces on commercial operations was measured, and three representative 24-h thermal regimens in the ∼15°C, ∼25°C, and ∼35°C ranges were chosen and emulated using a thermocycler. C. parvum oocysts suspended in deionized water were exposed to the temperature cycles, and their infectivity in mice was tested. Oral inoculation of 103 treated oocysts per neonatal B

Resumen

Ginseng has beneficial effects in cancer, diabetes and aging. There are two main varieties of ginseng: Panax ginseng (Korean ginseng) and Panax quinquefolius (American ginseng). There are anecdotal reports that American ginseng helps reduce body temperature, whereas Korean ginseng improves blood circulation and increases body temperature; however, their respective effects on body temperature and metabolic parameters have not been studied. We investigated body temperature and metabolic parameters in mice using a metabolic cage. After administering ginseng extracts acutely (single dose of 1000 m

Resumen

The aim of this study was to explore the “intensity-response” relationship in local moxibustion-like stimuli- (LMS-) modulated gastric motility and its underlying receptor mechanism. Based on the thermal pain threshold (43°C), 41°C, 43°C, and 45°C LMS were separately applied to ST36 or CV12 for 180 s among ASIC3 knockout (ASIC3−/−) mice, TRPV1 knockout (TRPV1−/−) mice, and their homologous wild-type C57BL/6 mice (n=8in each group). Gastric motility was continuously measured by an intrapyloric balloon, and the amplitude, integral, and frequency of gastric motility during LMS were compared with

Resumen

Mice lacking acyl-CoA:diacylglycerol acyltransferase 1 (DGAT1), a key enzyme in triglyceride synthesis, have increased energy expenditure and therefore are resistant to obesity. Because ambient temperature can significantly affect energy expenditure in mice, we undertook these studies to determine the effects of different ambient temperatures on energy expenditure, food intake, and thermoregulation in DGAT1-deficient [ Dgat1(−/−)] mice. Dgat1(−/−) mice had increased energy expenditure irrespective of changes in the ambient temperature. Although core temperature was normal, surface temperature

Resumen

Therapeutic hypothermia is of relevance to treatment of increased body temperature and brain injury, but drugs inducing selective, rapid, and safe cooling in humans are not available. Here, we show that injections of adenosine 5′-monophosphate (AMP), an endogenous nucleotide, promptly triggers hypothermia in mice by directly activating adenosine A1 receptors (A1R) within the preoptic area (POA) of the hypothalamus. Inhibition of constitutive degradation of brain extracellular AMP by targeting ecto 5′-nucleotidase, also suffices to prompt hypothermia in rodents. Accordingly, sensitivity of mice

Resumen

Heart rate (HR), body temperature (Temp), locomotor activity (LA), and oxygen consumption (O2C) were studied in awake mice lacking one or both of the adenosine A1 or A2A receptors (A1R or A2AR, respectively) using telemetry and respirometry, before and after caffeine administration. All parameters were lower during day than night and higher in females than males. When compared with wild-type (WT) littermates, HR was higher in male A1R knockout (A1RKO) mice but lower in A2ARKO mice and intermediate in A1-A2AR double KO mice.

Resumen

Hypoxia has been shown to rapidly increase triglycerides in mice by decreasing plasma lipoprotein clearance. However, the usual temperature of hypoxic exposure is below thermoneutrality for mice, which may increase thermogenesis and energy requirements, resulting in higher tissue lipid uptake. We hypothesize that decreased lipid clearance and ensuing hyperlipidemia are caused by hypoxic suppression of metabolism at cold temperatures and, therefore, would not occur at thermoneutrality. Twelve-week-old, male C57BL6/J mice were exposed to 6 h of 10% O2 at the usual temperature (22°C) or thermoneu

Resumen

The effects of E. coli endotoxin 0127 B8 on oxygen consumption, temperature, and on the activity of the proton conductance pathway in brown adipose tissue (BAT) were investigated in rats and mice. In rats an increase was observed in rectal and skin temperature, whole body oxygen consumption and GDP binding in BAT. In mice only the rise in rectal and skin temperature were significantly changed by endotoxin administration. These findings suggest that in some species BAT is involved in the production of endotoxin induced fever and increased energy expenditure.
