Previous research has demonstrated that emotional stimuli receive preferential processing in the brain. In the current study, functional magnetic resonance imaging was utilized to determine if emotion-specific responses are detectable in the cervical spinal cord. During the passive (i.e., non-motoric) perception of images, activity was detected in the left dorsal and right ventral spinal cord in response to negative emotional stimuli; however, this pattern was reversed in response to neutral and positive stimuli. Critically, during active motoric responses to images, there was greater activity in the ventral cervical spinal cord in response to negative emotional stimuli than to neutral stimuli. These results demonstrate preferential motor responses to negative emotional images by the spinal cord, likely indicating an enhancement of activity in response to threat.

Serotonin (5-HT) is a neurotransmitter found throughout the human body that regulates many physiological events arising from the brain and central nervous system (CNS), such as sleep and appetite. However, it has many other functions in systems outside. In addition to the routine expression of 5-HT7 receptors in CNS regions, such as the pituitary gland, spinal cord, and hippocampus, many studies have reported the expression of these receptors in pathological conditions outside.

Background: Awareness of the characteristics of glial fibrillary acidic protein autoantibody (GFAP-IgG) associated myelitis facilitates early diagnosis and treatment. We explored features in GFAP-IgG myelitis and compared them with those in myelitis associated with aquaporin-4 IgG (AQP4-IgG) and myelin oligodendrocyte glycoprotein IgG (MOG-IgG).
Methods: We retrospectively reviewed data from patients with GFAP-IgG myelitis at the First Affiliated Hospital of Zhengzhou University and Henan Children's Hospital from May 2018 to May 2023.

Microglia/macrophages participate in the development of and recovery from experimental autoimmune encephalomyelitis (EAE), and the macrophage M1 (pro-inflammatory)/M2 (anti-inflammatory) phase transition is involved in EAE disease progression. We evaluated the efficacy of crisdesalazine (a novel microsomal prostaglandin E2 synthase-1 inhibitor) in an EAE model, including its immune-regulating potency in lipopolysaccharide-stimulated macrophages, and its neuroprotective effects in a macrophage-neuronal co-culture system. Crisdesalazine significantly alleviated clinical symptoms, inhibited inflammatory cell infiltration and demyelination in the spinal cord, and altered the phase of microglial/macrophage and regulatory T cells.

Inflammation is a driving force of hematopoietic stem cells (HSCs) aging, causing irreversible exhaustion of functional HSCs. However, the underlying mechanism of HSCs erosion by inflammatory insult remains poorly understood. Here, we find that transient LPS exposure primes aged HSCs to undergo accelerated differentiation at the expense of self-renewal, leading to depletion of HSCs.
