Kouchek M, Takasusuki T, Terashima T, Yaksh TL, Xu Q (2013) Effects of intrathecal SNC80, a delta receptor ligand, on nociceptive threshold and dorsal horn substance p release. J Pharmacol Exp Ther 347(2):258-264. doi: 10.1124/jpet.113.206573 PMID: 23978562

Summary: In this work the authors utilized three different preclinical pain models to examine the effects of intrathecal administration of the DOR agonist SNC80. One strategy was to assess NK-1 receptor (NK1r) internalization using anti-NK1r (Cat. #AB-N33AP) in IHC at a 1:3000 dilution on cryosections. The data indicate that the transmitter release from small peptidergic afferents is an effect mediated by DOR in the spinal cord.

Johnson PL, Sajdyk TJ, Fitz SD, Hale MW, Lowry CA, Hay-Schmidt A, Shekhar A (2013) Angiotensin II’s role in sodium lactate-induced panic-like responses in rats with repeated urocortin 1 injections into the basolateral amygdala: amygdalar angiotensin receptors and panic. Prog Neuropsychopharmacol Biol Psychiatry 44:248-256. doi: 10.1016/j.pnpbp.2013.02.014 PMID: 23523745

Objective: To test the hypothesis that the subfornical organ (SFO) projects to the basolateral amygdala (BLA) and releases angiotensin-II (A-11) to mobilize panic responses.

Summary: The presence of AT-1R was confirmed in the BLA which, combined with previous data, suggests that A-II’s panicogenic effects in the BLA are AT-1R dependent.

Usage: Immunohistochemistry (1:250 to 1:500).

Smith MT, Woodruff TM, Wyse BD, Muralidharan A, Walther T (2013) A small molecule angiotensin II type 2 receptor (AT₂R) antagonist produces analgesia in a rat model of neuropathic pain by inhibition of p38 mitogen-activated protein kinase (MAPK) and p44/p42 MAPK activation in the dorsal root ganglia. Pain Med 14(10):1557-1568. doi: 10.1111/pme.12157 PMID: 23742186

Objective: To elucidate the mechanism through which EMA300, a small molecule antagonist of the angiotensin II type 2 receptor (AT2R) with >1,000-fold selectivity over the angiotensin II type 1 receptor, produces analgesia in a rodent model of neuropathic pain.

Summary: Augmented angiotensin II/AT2R signaling in the DRGs of CCI rats is attenuated by EMA300 to block p38 MAPK and p44/p42 MAPK activation, a mechanism with clinical validity for alleviating neuropathic pain.

Usage: Immunostaining (1:250), rat DRG sections

Summary: The hyperpolarization-activated cation current in the preBötzinger complex (preBötC) was identified as a critical component of respiratory rhythm. An anti-neurokinin 1 receptor antibody (Cat. #AB-N04 replaced by Cat. #AB-N33AP) at a 1:1000 dilution was used to identify preBötC neurons in the brainstem.

Neace CJ, Alderete JF (2013) Epitopes of the highly immunogenic trichomonas vaginalis alpha-actinin are serodiagnostic targets for both women and men. J Clin Microbiol 51(8):2483-2490. doi: 10.1128/JCM.00582-13 PMID: 23616456

Summary: Trichomonas vaginalis is an anaerobic protozoan that is the most common nonviral causative agent for sexually-transmitted infections. The presence of T. vaginalis in men is usually asymptomatic, making it difficult to assess exposure to the organism. The authors examined sera from exposed individuals for reactivity to specific epitopes of trichomonad α-actinin. A recombinant version of trichonomad α-actinin was constructed and detected using Anti-6His (Cat. #AB-213). Some epitopes were reactive with sera from both men and women, making them potential diagnostic targets.

Objective: To immunohistochemically differentiate the angiotensin receptor subtypes: AT-1ARa, AT-1ARb, and AT-2R.

Summary: Antibodies that can differentiate the three different angiotensin II receptor subtypes in the rat were used to immunohistochemically label angiotensin II receptor subtype-like immunoreactivity in the rat adrenal, pituitary, and brain. The pattern of staining corroborates mRNA, radioligand binding, and functional studies of adrenal and anterior pituitary angiotensin receptors.

Usage: Western blot (1:500), immunofluorescence (1:500), immunocytochemistry (AB-N25AP and AB-N26AP at 1:500, AB-N28AP at 1:2000).

Koch H, Zanella S, Elsen GE, Smith L, Doi A, Garcia AJr, Wei AD, Xun R, Kirsch S, Gomez CM, Hevner RF, Ramirez JM (2013) Stable respiratory activity requires both P/Q-type and N-type voltage-gated calcium channels. J Neurosci 33(8):3633-3645. doi: 10.1523/JNEUROSCI.6390-11.2013 PMID: 23426690

Summary: Pharmacological experiments have suggested that sighs and normal respiration are highly dependent on calcium currents carried by P/Q channels. Using transgenic mice missing the Cav2.1 pore-forming α1A subunit the authors demonstrate that loss of P/Q-type calcium channels results in compromised breathing, sighing, neuromodulation, and leads to early death. A neurokinin-1 receptor antibody (Cat. #AB-N33AP) at a 1:500 dilution was used for immunohistochemistry in this work.

Summary: A major hurdle to clear in the fight against bioterrorism is the ability to identify various biowarfare agents. One of the more difficult substances to identify is ricin. This work describes the use of single domain antibodies to identify ricin in a microring resonator array assay. Saporin (Cat. #PR-01) along with affinity purified chicken anti-saporin (Cat. #AB-17AP) were used as controls when constructing the assay. The results demonstrate the feasibility of using microring resonator arrays for the detection of biowarfare agents.
