Drug repurposing screen identifies novel anti-inflammatory activity of sunitinib in macrophages.

Inflammation is a driver of human disease and an unmet clinical need exists for new anti-inflammatory medicines. As a key cell type in both acute and chronic inflammatory pathologies, macrophages are an appealing therapeutic target for anti-inflammatory medicines. Drug repurposing - the use of existing medicines for novel indications - is an attractive strategy for the identification of new anti-inflammatory medicines with reduced development costs and lower failure rates than de novo drug discovery.

Immunomodulatory leptin receptor sympathetic perineurial barrier cells protect against obesity by facilitating brown adipose tissue thermogenesis.

Adipose tissues (ATs) are innervated by sympathetic nerves, which drive reduction of fat mass via lipolysis and thermogenesis. Here, we report a population of immunomodulatory leptin receptor-positive (LepR) sympathetic perineurial barrier cells (SPCs) present in mice and humans, which uniquely co-express Lepr and interleukin-33 (Il33) and ensheath AT sympathetic axon bundles. Brown ATs (BATs) of mice lacking IL-33 in SPCs (SPC) had fewer regulatory T (Treg) cells and eosinophils, resulting in increased BAT inflammation.

Old and "hangry" monocytes turn from friend to foe under assault.

Fasting is known to impact monocyte dynamics and phenotype, but the mechanics and functional significance of this response remain unclear. In this issue of Immunity, Janssen and colleagues demonstrate that fasting and re-feeding causes monocytes to re-enter the bone marrow and alter the host response to infection.

Relating behaviours and therapeutic actions during AVATAR therapy dialogue: An observational study.

Objectives: AVATAR therapy is a novel relational approach to working with distressing voices by engaging individuals in direct dialogue with a digital representation of their persecutory voice (the avatar). Critical to this approach is the avatar transition from abusive to conciliatory during the course of therapy. To date, no observational study has examined the moment-to-moment dialogical exchanges of this innovative therapy.

The role of characterisation in everyday voice engagement and AVATAR therapy dialogue.

Background: Voices are commonly experienced as communication with a personified 'other' with ascribed attitudes, intentionality and personality (their own 'character'). Phenomenological work exploring voice characterisation informs a new wave of relational therapies. To date, no study has investigated the role of characterisation in behavioural engagement with voices or within psychological therapy for distressing voices.

Randomised controlled trial to improve health and reduce substance use in established psychosis (IMPaCT): cost-effectiveness of integrated psychosocial health promotion.

Background: There is mounting evidence that people with severe mental illness have unhealthy lifestyles, high rates of cardiovascular and metabolic diseases, and greater risk of early mortality. This study aimed to assess the cost-effectiveness of a health promotion intervention seeking to improve physical health and reduce substance use in people with psychosis.

Methods: Participants with a psychotic disorder, aged 18-65 years old and registered on an enhanced care approach programme or equivalent were recruited from community mental health teams in six mental health trusts in England.
