Evaluation of fluorine-18-fluorodeoxyglucose PET/computed tomography and human epithelial growth factor receptor 2 expression in treatment-naive patients with lung adenocarcinoma.
Human epithelial growth factor receptor 2 (HER2) is overexpressed in several types of cancers. The correlation between tumor glucose activity and HER2 expression can vary. This study is a retrospective investigation of fluorine-18-fluorodeoxyglucose PET/computed tomography (18F-FDG PET/CT) and HER2 expression status in patients with lung adenocarcinoma.Yuan Li, Xiaodong Wu, Juanjuan Fang, Qingping Zhao, Yan Huang, Lei Jiang

Identification of anti-lipoarabinomannan antibodies against mannan core and their effects on phagocytosis of mycobacteria by human neutrophils.
Mycobacterium tuberculosis (MTB) and M. avium-intracellulare complex (MAC) enter host phagocytes, such as neutrophils through lipoarabinomannan (LAM) binding to pattern-recognition receptors, inducing innate immune responses including phagocytosis. Phagocytosis of mycobacteria by human neutrophils depends on the binding of α(1 â 2)-monomannose branching α(1 â 6)-mannan core of LAM/lipomannan (LM), a common component among mycobacterial species, to lactosylceramide (LacCer)-enriched lipid microdomains. We investigated the binding specificities of several anti-LAM antibodies (Abs) to LAMs/LM and found anti-LAM monoclonal IgMs TMDU3 and LA066 were directed against mannan core. Each IgM showed different binding specificity to mannan core. Confocal and stimulated emission depletion microscopy revealed TMDU3 and LA066 strongly bind to MTB and MAC, respectively. Flow cytometric analysis revealed human neutrophils do not express Dectin-2, DC-SIGN or mannose receptor. Furthermore, neutrophil phagocytosis of mycobacteria was markedly inhibited by TMDU3 and LA066, respectively. Similarly, treatment of each mAb with neutrophils reduced the numbers of intracellular MAC. Together, our results suggest that the interaction of LacCer-enriched lipid microdomains with mannan core and its blocking are therapeutic or diagnostic targets for both TB and non-tuberculous mycobacteria infection.Hitoshi Nakayama, Eriko Oshima, Tomomi Hotta, Kei Hanafusa, Kota Nakamura, Noriko Yokoyama, Hideoki Ogawa, Kenji Takamori, Kazuhisa Iwabuchi

Acute restraint stress redirects prefrontal cortex circuit function through mGlu receptor plasticity on somatostatin-expressing interneurons.
Inhibitory interneurons orchestrate prefrontal cortex (PFC) activity, but we have a limited understanding of the molecular and experience-dependent mechanisms that regulate synaptic plasticity across PFC microcircuits. We discovered that mGlu receptor activation facilitates long-term potentiation at synapses from the basolateral amygdala (BLA) onto somatostatin-expressing interneurons (SST-INs) in mice. This plasticity appeared to be recruited during acute restraint stress, which induced intracellular calcium mobilization within SST-INs and rapidly potentiated postsynaptic strength onto SST-INs. Restraint stress and mGlu receptor activation each augmented BLA recruitment of SST-IN phasic feedforward inhibition, shunting information from other excitatory inputs, including the mediodorsal thalamus. Finally, studies using cell-type-specific mGlu receptor knockout mice revealed that mGlu receptor function in SST-expressing cells is necessary for restraint stress-induced changes to PFC physiology and related behaviors. These findings provide new insights into interneuron-specific synaptic plasticity mechanisms and suggest that SST-IN microcircuits may be promising targets for treating stress-induced psychiatric diseases.Max E Joffe, James Maksymetz, Joseph R Luschinger, Shalini Dogra, Anthony S Ferranti, Deborah J Luessen, Isabel M Gallinger, Zixiu Xiang, Hannah Branthwaite, Patrick R Melugin, Kellie M Williford, Samuel W Centanni, Brenda C Shields, Craig W Lindsley, Erin S Calipari, Cody A Siciliano, Colleen M Niswender, Michael R Tadross, Danny G Winder, P Jeffrey Conn

R-type voltage-gated Ca channels mediate A-type K current regulation of synaptic input in hippocampal dendrites.
The subthreshold voltage-gated transient K current (I) carried by pore-forming Kv4.2 subunits regulates the propagation of synaptic input, dendritic excitability, and synaptic plasticity in CA1 pyramidal neuron dendrites of the hippocampus. We report that the Ca channel subunit Cav2.3 regulates I in this cell type. We initially identified Cav2.3 as a Kv4.2-interacting protein in a proteomic screen and we confirmed Cav2.3-Kv4.2 complex association using multiple techniques. Functionally, Cav2.3 Ca-entry increases Kv4.2-mediated whole-cell current due to an increase in Kv4.2 surface expression. Using pharmacology and Cav2.3 knockout mice, we show that Cav2.3 regulates the dendritic gradient of I. Furthermore, the loss of Cav2.3 function leads to the enhancement of AMPA receptor-mediated synaptic currents and NMDA receptor-mediated spine Ca influx. These results propose that Cav2.3 and Kv4.2 are integral constituents of an ion channel complex that affects synaptic function in the hippocampus.Jonathan G Murphy, Jakob J Gutzmann, Lin Lin, Jiahua Hu, Ronald S Petralia, Ya-Xian Wang, Dax A Hoffman

CXCR3 regulates stem and proliferative CD8+ T cells during chronic infection by promoting interactions with DCs in splenic bridging channels.
Production of effector CD8+ T cells during persistent infection requires a stable pool of stem-like cells that can give rise to effector cells via a proliferative intermediate population. In infection models marked by T cell exhaustion, this process can be transiently induced by checkpoint blockade but occurs spontaneously in mice chronically infected with the protozoan intracellular parasite Toxoplasma gondii. We observe distinct locations for parasite-specific T cell subsets, implying a link between differentiation and anatomical niches in the spleen. Loss of the chemokine receptor CXCR3 on T cells does not prevent white pulp-to-red pulp migration but reduces interactions with CXCR3 ligand-producing dendritic cells (DCs) and impairs memory-to-intermediate transition, leading to a buildup of memory T cells in the red pulp. Thus, CXCR3 increases T cell exposure to differentiation-inducing signals during red pulp migration, providing a dynamic mechanism for modulating effector differentiation in response to environmental signals.Derek J Bangs, Alexandra Tsitsiklis, Zoë Steier, Shiao Wei Chan, James Kaminski, Aaron Streets, Nir Yosef, Ellen A Robey

Do catecholaminergic TrkC DRG neurons represent a class of cardiovascular enteroceptor?
In a recent issue of Cell Reports, Morelli et al. (2021) identify a subpopulation of mechanosensitive peripheral sensory neurons that coexpress tyrosine hydroxylase (TH) and tropomyosin receptor kinase C (TrkC) and innervate cutaneous arterioles. They show that activation of TrkC sensory neurons causes cutaneous vasoconstriction and, most remarkably, that their lesion is associated with sudden death of an undetermined cause, preceded by a progressive drop in blood pressure, and conclude that TrkC TH neurons represent a baroreceptor class of homeostatic enteroceptor. This represents a radical departure from current consensus models for the central control of blood pressure. Here, we offer an alternative perspective on their findings and suggest priorities for further investigation. This Matters Arising paper is in response to Morelli et al. (2021), published in Cell Reports. See also the response by Heppenstall et al. (2022), published in this issue.Simon McMullan, Peter G R Burke, Cara M Hildreth
