Summary: The authors investigated the interactions of pro-survival and pro-apoptotic receptors in Programmed Cell Death (PCD) using the sympathetic nervous system as a model. They demonstrate that Ret, a receptor tyrosine kinase required for the survival of many neuronal populations, is restricted to a subset of degenerating neurons that rapidly undergo apoptosis.

Usage: Proximity ligation assays (1:500); Western blotting (1:1,000)

Objective: To show that myoepithelial cells (MECs) of the submucosal glands (SMGs) proliferate and migrate to repopulate the airway surface epithelium (SE) in multiple injury models.

Summary: SMG-like cells appear on the SE of extra-and intra-lobular airways of large animal lungs following severe injury. The transcription factor SOX9 is necessary for MEC plasticity in airway regeneration.

Gibon J, Buckley S, Unsain N, Kaartinen V, Séguéla P, Barker P (2015) proBDNF and p75NTR control excitability and persistent firing of cortical pyramidal neurons. J Neurosci 35:9741-9753. doi: 10.1523/JNEUROSCI.4655-14.2015 PMID: 26134656

Summary: Principal neurons in the entorhinal cortex (EC) display persistent firing (PF) during working-memory tasks. Much of the communication between the hippocampus and the neocortex passes through the EC, and the EC also receives some cholinergic input from the medial septum and diagonal band of Broca. In this work the authors investigated the role of pro-brain-derived neurotrophic factor (proBDNF) and the p75 receptor in excitability and PF in the EC. The authors propose the proBDNF/p75 system as a regulator for pyramidal neuron excitability and PF in the EC, preventing runaway activity. Some of the western blot and current-clamp data was generated using Anti-p75 (Cat. #AB-N01; no concentration information provided).

Summary: During development bone morphogenetic protein 9 (BMP9) induces the cholinergic phenotype in the basal forebrain. The authors investigated the use of BMP9 as a treatment of basal forebrain cholinergic degeneration, such as is seen in Alzheimer’s disease (AD). Transgenic mice displaying AD phenotypes and expressing GFP in cholinergic neurons received icv infusions of BMP9, and several cholinergic markers were assessed. Anti-p75NTR (Cat. #AB-N01) was used in immunoblotting at a 1:3000 dilution to measure p75 levels. The results demonstrate the protective and therapeutic activity of BMP9 on AD symptoms.

Summary: Chronic overexpression of nerve growth factor (NGF) in the urinary bladder results in neuronal sprouting, increased voiding frequency, and referred somatic hypersensitivity. The authors investigated several growth factor and receptor responses to chronic overexpression of NGF. A p75 antibody (Cat. #AB-N01) was used to obtain the immunohistochemistry data. The data suggest that changes due to NGF overexpression may be a compensatory attempt to reduce voiding frequency.

Summary: Inflammation, which can lead to pain hypersensitivity, not only elevates NGF levels, but also can increase the sensitivity of high-threshold receptors. NGF is thought to be a major contributor to heightened pain states due to inflammation, and in this work the authors investigated the role that the p75 neurotrophin receptor might play in NGF-induced hyperalgesia. 30 minutes prior to injection with Freund’s adjuvant, mice received 10 μl of polyclonal anti-p75 (Cat. #AB-N01) into the plantar surface of the paw. The antibody administration blocked hyperalgesia, indicating that p75 plays an important role in inflammation-induced hyperalgesia.
