Chronic intake of High Fat Diet (HFD) has the potential of causing a number of metabolic disorders. It is also theorized to be involved in perturbation of gut microbiota. Cannabididol (CBD) and omega 3 are known to possess a number of medicinal usefulness. Their combined use in experimental interventions is quite limited. A total of 15 mice were used for this research divided into three groups of five animals each. Group 1 was administered water and normal chow ad libidum. Group 2 had HFD and water ad libidum. Group 3 had HFD plus CBD (10 mg/kg) and omega 3 (200 mg/kg) all for a total of 12 weeks. They were tested on the elevated plus maze (EPM) and average entry time into the closed arm was recorded. They were also tested on the Y-maze and spontaneous alternations were measured. Thereafter animals were sacrificed and faecal content in the caecum was collected in sterile bottles and cultured for E. coli count. It was found that HFD group at p value E. coli count (2.4 × 106 ± 4.5) compared to group 1 (1.4 × 106 ± 5.6) and group 3 (1.42 × 106 ± 6.3). The findings revealed that HFD enhanced gut E. coli overgrowth which was reduced by CBD and Omega 3. The memory impairment and anxiety induction by HFD was also significantly ameliorated by CBD and omega 3. E. coli known to be implicated in dementia induction was suppressed by the interventions. Possible mechanisms proposed are actions of CBD and omega 3 on CB1, TRVP and 5HT receptors in reducing anxiety and their antioxidant/anti-inflammatory actions in mitigating the neuro-inflammatory effect of HFD and immune hyperstimulation of E. coli via the gutbrain-axis.

Chronic Physical Stress Does Not Interact with Epstein-Barr Virus (EBV)-Encoded Dutpase to Alter the Sickness Response

Most adult humans have been infected with Epstein-Barr virus (EBV), which is thought to contribute to the development of chronic fatigue syndrome. Stress is known to influence the immune system and can exacerbate the sickness response. Although a role for psychological stress in the sickness response, particularly in combination with EBV-encoded deoxyuridine triphosphate nucleotidohydrolase (dUTPase) has been established, and the role of physical stressors in these interactions remains unspecified. In this study, we seek to determine the interaction of chronic physical (swim) stress and EBV-encoded dUTPase injection. We hypothesize that a chronic physical stressor will exacerbate the sickness response following EBV-encoded dUTPase injection. To test this hypothesis mice receive daily injections of EBV-encoded dUTPase or vehicle and are subjected to 15 min of swim stress each day for 14 days or left unmanipulated. On the final evening of injections mice undergo behavioral testing. EBV-encoded dUTPase injection alone produces some sickness behaviors. The physical swimming stress does not alter the sickness response.

Restraint Induces Sickness Responses Independent of Injection with Epstein-Barr Virus (EBV)-Encoded dUTPase

Journal of Behavioral and Brain Science 2014年第11期4卷 491-505页

Most adult humans have been infected by Epstein-Barr virus (EBV), a putative cause of chronic fatigue syndrome, and carry latent EBV. The EBV-encoded dUTPase can induce sickness responses in mice and chronic stress exacerbates this response. Because individuals often adapt to chronic stress, we tested the hypothesis that acute restraint stress would potentiate these sickness responses elicited by EBV-encoded dUTPase. Male CD-1 mice were injected daily for one or three days with either saline or EBV-encoded dUTPase. Additionally, mice from each condition were either restrained for three hours daily or left undisturbed during the light phase when mice are inactive. Restraint decreased weight gain during the one- and three-day experiments. Restraint in saline injected mice increased anxiety-like behavior in the open field during the three-day experiment. There were no behavioral differences during the one-day experiment. Restraint stress had no effect when experienced acutely on one day, but did produce a sickness response after three days of exposure regardless of saline or dUTPase injection. In contrast to the effects of chronic stress and EBV-encoded dUTPase on the sickness response, acute stress did not affect sickness responses in association with EBV-encoded dUTPase. Thus, dUTPase does not appear to provoke the same sickness responses after acute stress as compared to chronic stress.
