2018 Targeting Trends Review

Donnelly CR, Gabreski NA, Suh EB, Chowdhury M, Pierchala BA (2018) Non-canonical Ret signaling augments p75-mediated cell death in developing sympathetic neurons. J Cell Biol 217:327. doi: 10.1083/jcb.201703120 PMID: 30018091

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)

Tools to Study Programmed Cell Death

Shumilov K, Real MÁ, Valderrama-Carvajal A, Rivera A (2018) Selective ablation of striatal striosomes produces the deregulation of dopamine nigrostriatal pathway. PLoS One 13:e0203135. doi: 10.1371/journal.pone.0203135

Objective: To increase knowledge in the role of the striosomal projection onto the dopamine neurons of the SNc and its impact on the nigrostriatal dopamine pathway.

Summary: Results highlight the key function of the striosomes for maintenance of the striatal dopamine tone and contribute to the understanding of their involvement in some neurological disorders such as Huntington’s disease.

Usage: Unilateral intrastriatal 2-μl injections of Dermorphin-SAP (17 μg/μl in saline) were performed to induce the selective ablation of MOR-expressing neurons in the striosomal compartment.

Zhang Z, Jiang SM, Ma YP, Dai PL, Wang YN, Zou GM, Gao HM, Yang Y, Li WG (2019) Expression of the intrarenal angiotensin receptor and the role of renin-angiotensin system inhibitors in IgA nephropathy. Mol Cell Biochem 453:103-110. doi: 10.1007/s11010-018-3435-4 PMID: 30159797

Objective: To investigate the role of intrarenal renin-angiotensin system (RAS) in the development of human kidney disease. Patients with IgA nephropathy (IgAN) were screened and their clinical characteristics analyzed.

Summary: Overexpression of AT1R on the mesangial cells of IgAN patients is associated with mesangial cell proliferation, glomerular segmental sclerosis, and crescent formation.

Usage: immunohistochemistry (1:500)

Therap Adv Gastroenterol 11:1-22. doi: 10.1177/1756284818793558

Objective: To analyze the significance of the IDO:Treg axis for inducing and maintaining mucosal healing in ulcerative colitis (UC).

Summary: IDO-dependent expansion of endogenous Tregs should be explored as a new approach for induction and maintenance of mucosal healing in patients with UC.

Usage: DSS-treated BALB/c mice were injected with Anti-CD103-SAP (2 mg/kg, intraperitoneally).

Objective: To obtain unambiguous information about retinal processing.

Summary: Results establish a foundation for future application of intersectional strategies in the retina and retino-recipient regions.

Usage: Immunohistochemistry 1:1000.

Objective: Discover to what extent the cholinergic versus non‐cholinergic basal forebrain projection neurones contribute to the arousing action of glutamate.

Summary: Destruction of the basal forebrain cholinergic neurons did not abolish the wake‐enhancing action of NMDA. Thus, the cholinergic basal forebrain structures are not essential for the mediation of the arousing action of glutamate.

Usage: 0.23 μg 192 IgG‐SAP was administered into the basal forebrain.

Objective: To determine the involvement of orexin cells from the lateral hypothalamus/perifornical area (LH/PeF) on breathing.

Summary: The degeneration of orexinergic neurons in this model of PD can be related to impaired chemoreceptor function in the dark phase.

Usage: For lesions of LH/PeF, two injections of Orexin-B-SAP or Rabbit IgG-SAP (100 ng/μl) were made into the lateral hypothalamus / perifornical area (LH/PeF).
