Docosanoid signaling modulates corneal nerve regeneration: effect on tear secretion, wound healing, and neuropathic pain
Thang L. Pham and Haydee E.P. Bazan
COVER: The cornea is densely innervated, mainly by sensory nerves of the ophthalmic branch of the trigeminal ganglion (TG). These nerves play a pivotal role in corneal health and in the pathological genesis of diseases such as neurotrophic keratitis, corneal ulceration, dry eye disease, and neuropathic pain. Using animal models of corneal nerve damage, treatment with pigment epithelium-derived factor (PEDF) plus docosahexaenoic acid (DHA) stimulates nerve regeneration through a mechanism that involves the synthesis of docosanoids including neuroprotectin D1 (NPD1) and the new resolvin stereoisomer RvD6i. These lipid mediators activate the corneal-TG axis, resulting in an increase of corneal wound healing, sensation recovery, and tear secretion without any exacerbation of corneal pain. The actions of these docosanoids open avenues of therapeutic exploration to re-establish corneal homeostasis in many clinical pathologies. (See Pham and Bazan.)

Acetylcholine, via SK Channels, Regulates CA3–CA1 Coupling
Crescent L. Combe, Carmen C. Canavier, and Sonia Gasparini
COVER: Sodium-coupled neutral amino acid transporters SNAT1 and SNAT2 are considered to be the neuronal system A transporters that supply glutamine to neurons for synaptic transmission. SNAT1 is enriched in all parvalbumin-containing inhibitory neurons in the cortex and hippocampus, while SNAT2 is predominant in all pyramidal excitatory neurons. However, SNAT1 and SNAT2 are confined to the cell soma and proximal dendritic region and both are excluded from axon terminals suggesting that other unidentified neuronal glutamine transporters expressed in synapses support GABA and glutamatergic transmission. Shown is a merged confocal projection image (400X) of immunohistochemical staining in the rat hippocampal CA1 region for SNAT2 (red) with VGLUT1 (green). Non-biased imaging was provided by the LSUHSC Morphology and Imaging Core.

COVER: MALDI MS imaging of the macular region of the human retina. Merged MALDI positive ion images from a cryo-section of a 47-year-old donor retina are shown at the left. These images show unique lipid layering of phosphatidylcholine (PC) molecules: m/z 986.6 PC(50a:11)+Na, green; m/z 958.6 PC(48a:11)+Na, blue; and m/z 1070.6 PC(56:11)+Na, red. These are PCs composed of a long chain- and a very long-chain polyunsaturated fatty acid. Docosahexaenoic acid (DHA; 22:6) is located at the sn-2 position of retina PC molecules. The red label corresponds to the photoreceptor layer, the green label to the inner retina. Negative ion lipids are shown at top right (red is photoreceptor layer, green is inner retina). Very long chain polyunsaturated fatty acid-containing PCs from this same section are shown at middle right. Image at bottom right illustrates lipid stratification with a ceramide in the retinal pigment epithelium. (See Zemski Berry et al., p. 504.)

Association of Protein Tyrosine Phosphatases (PTPs)-1B with c-Met Receptor and Modulation of Corneal Epithelial Wound Healing
Azucena Kakazu, Guru Sharma, and Haydee E. P. Bazan
COVER: Colocalization of the hepatocyte growth factor receptor (c-Met) and protein tyrosine phosphatase 1B (PTP1B) in human corneal epithelial cells. The cells were fixed with paraformaldehyde and immunostaining with PTP1B (green) and c-Met (red) . Hoechst was used for nuclear counterstained. The colocalization seems to be important for silencing c-Met signaling inside the cells. Azucena Kakazu, Guru Sharma and Haydee E.P. Bazan

COVER: Triple immunofluorescent staining reveals homeostatic scaling of vesicular glutamate transporters at excitatory synapses. Hyperexcitation in neocortical neuronal networks caused downregulation of VGLUT1 (red) at most synaptic terminals that face postsynaptic density 95 (blue), whereas VGLUT2 increased in some VGLUT1-containing synapses (yellow/blue) and at other sites (green/blue, green only). VGLUT2 is coexpressed with VGLUT1 in a novel class of excitatory neurons in the cerebral cortex. Their differential synaptic regulation may serve as negative or positive feedback regulators for neocortical excitatory transmission. For details, see the article by De Gois et al. in the August 3, 2005 issue (pages 7121–7133).

COVER: Simplified cartoon of phospholipases A2 at the synapse. Depolarization triggers release of glutamate, which in turn binds to the N-methyl-D-aspartate receptor and increases calcium influx into the postsynaptic neuron. Phospholipases A2 release arachidonic acid (AA), docosahexaenoic acid (DHA), and lyso-platelet-activating factor (lyso-PAF), the precursor of platelet-activating factor. sPLA2, secretory phospholipase A2.
