    Glucocorticoid receptor-PPARα axis in fetal mouse liver prepares neonates for milk lipid catabolism

    Gianpaolo Rando et al.
    Glucocorticoid receptor directly regulates the transcriptional activity of peroxisome proliferator-activated alpha (PPARα) before birth in anticipation of the sudden shifts in the postnatal nutrient source and metabolic demands.

    Somatostatin binds to the human amyloid β peptide and favors the formation of distinct oligomers

    Hansen Wang et al.
    The cyclic neuropeptide somatostatin binds to human Aβ1-42 through an interface that critically relies on a specific tryptophan, thereby blocking the propensity of Aβ to aggregate, a critical step in the pathobiology of Alzheimer's disease.

    A single pair of neurons links sleep to memory consolidation in Drosophila melanogaster

    Paula R Haynes et al.
    Dorsal paired medial neurons, which are required for memory consolidation, promote sleep by inhibiting the excitation of mushroom body neurons.

    Multiplexed coding by cerebellar Purkinje neurons

    Sungho Hong et al.
    Cerebellar Purkinje neurons use a multiplexed simple spike code combining synchrony/spike time and firing rate, with each component encoding distinct information about movements such as motion onset timing and kinematics.

    An engineered monomer binding-protein for α-synuclein efficiently inhibits the proliferation of amyloid fibrils

    Emil Dandanell Agerschou et al.
    The high affinity α-synuclein-monomer binder AS69 converts into a strong sub-stoichiometric inhibitor of nucleation processes upon formation of the AS69-α-synuclein complex, achieving reduced aggregation in vitro and in vivo.

    Hippocampal activation is associated with longitudinal amyloid accumulation and cognitive decline

    Stephanie L Leal et al.
    Cognitively normal older adults show a positive relationship between neural activity during memory encoding and brain β-amyloid deposition rate over the subsequent 3-4 years, supporting preclinical data that associates neural activity with β-amyloid deposition.

    Cerebral blood flow and cerebrovascular reactivity are preserved in a mouse model of cerebral microvascular amyloidosis

    Leon P Munting et al.
    The causal link between capillary amyloid‑β accumulation in the brain and cerebrovascular dysfunction, previously established in the Tg‑SwDI mouse model, is to be mitigated and remains to be fully uncovered.

    Intestinal infection regulates behavior and learning via neuroendocrine signaling

    Jogender Singh, Alejandro Aballay
    Feedback from the intestine during infection can modulate the behavior, learning, and microbial perception of the host.

    CD40 is a major regulator of dendrite growth from developing excitatory and inhibitory neurons

    Paulina Carriba, Alun M Davies
    CD40-activated CD40L-mediated reverse signalling has strikingly opposite effects on the growth of excitatory and inhibitory neuron dendrites in the developing brain of mice.

    Reversible promoter methylation determines fluctuating expression of acute phase proteins

    Shi-Chao Zhang et al.
    DNA methylation status can be exploited to finely and reversibly tune the expression of highly inducible genes with CpG-poor promoters in response to environmental cues.
