Brain 145(1):154-167. doi: 10.1093/brain/awab239

Summary: There is strong comorbidity between chronic pain and depression. This study explores how this comorbidity occurs. The authors refer to published research that shows icv administration of anti-DBH-SAP or intra-LC administration of lidocaine dampened the evoked pain in conditions of long-term nerve-injury. However, icv injection of anti-DBH-SAP disrupts all noradrenergic nuclei (A1-A7), some of which contribute to sensorial hypersensitivity.

Objective: To characterize the effects of propofol on the profile of sleep–wake states and cortical electroencephalogram (EEG) power spectral density in rats following intraperitoneal injection.

Summary: The high dose of propofol produced high-quality sleep by increasing SWS2, whereas the medium dose produced fragmented and low-quality sleep by disrupting the continuity of wakefulness.

Usage: Bilateral injection of Orexin-SAP (92 and 184 ng/ml, 0.25 ml in the ventral tegmental area and 0.5 ml in the substantia nigra) of rats induced insomnia, as well as hyperactivity and stereotypic movements

Objective: To explore whether BYD plays a protective role against heart failure (HF) by attenuating cardiac hypertrophy (CH) via the ANKRD1-ERK/GATA4 pathway.

Summary: BYD ameliorates CH and improves HF through the ANKRD1-ERK/GATA4 pathway, providing a novel therapeutic option for the treatment of HF.

Objective: To describe the role of TRP vanilloid 1 (TRPV1) and TRP ankyrin 1 (TRPA1) involved in cancer pain mechanisms.

Summary: Several studies have revealed that the administration of TRPV1 or TRPA1 agonists/antagonists and TRPV1 or TRPA1 knockdown reduced sensitivity to nociception in cancer pain models. Thus, TRP channels are potential targets for managing cancer-related pain syndromes.

Objective: To test the hypothesis that Edinger-Westphal nucleus (EWcp) integrates multimodal signals (stress, thermal, metabolic, endocrine, etc.) and modulates the sympathetic output simultaneously to multiple effector organs to maintain energy homeostasis under different conditions that require adjustments of energy demands.

Summary: Besides its role in feeding/metabolic control and addiction, EWcp is involved in several important functions that are ultimately related to different aspects of stress responses, as well as stress coping and adaptation.

Objective: To study the effects and associated mechanism of hippocampal proBDNF in a lipopolysaccharide (LPS)-induced sepsis-associated encephalopathy (SAE) mouse model.

Summary: Mice showed cognitive dysfunction after LPS injection. The expression of proBDNF and its receptor, p75NTR, was increased in the hippocampus. The levels of BDNF and its receptor, TrkB, were decreased. An intrahippocampal or intraperitoneal injection of anti-proBDNF antibody ameliorated LPS-induced cognitive dysfunction.

Summary: Review of the use of focused ultrasound, in combination with circulating microbubbles, can be used to transiently and noninvasively increase cerebrovascular permeability with a high level of spatial precision. For minutes to hours following sonication, drugs can be administered systemically to extravasate in the targeted brain regions and exert a therapeutic effect, after which permeability returns to baseline levels.

Usage: Shin et al. reported improved spatial memory following FUS+MB exposure in a rat model of cholinergic neuron degeneration. 192-IgG-SAP was injected bilaterally into the lateral ventricle (4  μl at a concentration of 0.63  μg/μl at a rate of 1 μl/min).

Objective: To investigate the molecular mechanisms regulating how basal cells contribute to adult tissue regeneration by shifting from slow cycling to proliferating and subsequently back to slow cycling.

Summary: TGF-β-Id2 axis commonly regulates the proliferation transitions in basal cells during development and regeneration, and its fine-tuning is critical for normal regeneration while avoiding basal cell hyperplasia.

Objective: To test the hypothesis that a neuronal population postsynaptic to nasal sensory neurons mediates sneezing.

Summary: Chemical activation of neuromedin B (NMB)-sensitive neurons elicits action potentials in caudal ventral respiratory group (cVRG) neurons and leads to sneezing behavior. This study delineates a peptidergic pathway mediating sneezing, providing molecular insights into the sneezing reflex arc.

Usage: Microinjection of NMB-saporin into the sneeze-evoking region abolished the sneezing responses to capsaicin and histamine.
