Summary: P2YR’s are metabotropic purinergic receptors found in some parts of the CNS. A subtype of this receptor excites rhythm generating networks in the preBötzinger complex. In order to better understand the role of these receptors in modulation of motor output the authors used brainstem-spinal cord and medullary slice preparations from neonatal rats to investigate P2Y1R signaling on specific neurons that innervate diaphragm and airway muscles. Anti-NK1r (Cat. #AB-N33AP) at a 1:1000 dilution was used during the immunohistochemistry. The data suggest that loss of purinergic modulation contributes to motoneuron excitability.

Genes Dev 28:1429-1444. doi: 10.1101/gad.242131.114 PMID: 24990963

Summary: Members of the FOXO family are thought to act as tumor suppressor genes. In this work the authors investigated the hydroxylation of FOXO3a by EglN2. This hydroxylation pushes FOXO3a toward a protosomal degradation pathway. Loss of FOXO3a in turn allows the accumulation of Cyclin D1, which has been found to be overexpressed in some breast cancers. Some of the data were generated using immunoblots with anti-transhydroxylated proline (Cat. #AB-T044).

Summary: The authors used a mouse model of ‘retinal stroke’ to better delineate the optokinetic response deficits at the cellular level. Damage was found in the processes of starburst amacrine cells (SACs), and to a lesser extent, the dendrites. Anti-melanopsin (Cat. #AB-N38) at 1:2500 was used for immunohistochemistry.

Summary: The ferret has become a more common animal model in auditory neuroscience. Unlike rodent models, however, anatomical data describing the organization of the basal forebrain cholinergic system and its projections to the auditory cortex have not been well characterized. Using a variety of methods the authors mapped the architecture of the ferret basal forebrain. IHC was done with several antibodies including anti-ChAT (Cat. #AB-N34AP; 1:1000) and anti-NGFr (Cat. #AB-N07; 1:500). Animals also received 17 μg of ME20.4-SAP (Cat. #IT-15) in a total of 17 injections into the ectosylvian gyrus. The results indicate that acetylcholine is most likely involved in modulation of auditory processing.

Am J Physiol Renal Physiol 306:F1462-1476. doi: 10.1152/ajprenal.00623.2013 PMID: 24761004

Summary: The authors utilized a mouse model for homocystinuria in order to examine renal amino acid reabsorbtion. Some of the immunohistochemistry experiments used anti-Met (Cat. #AB-T036). It was found that loss of cystathionine β-synthase causes hyperexcretion of both glucogenic and ketogenic neutral amino acids, as well as histidine.

Summary: The high affinity nerve growth factor receptor, trkA, plays an intrinsic role in the regulation of various aspects of the mammalian nervous system. The post-translational attachment of ubiquitin to trkA plays a role in the final disposition and function of many proteins; in this work the authors investigate the result of trkA ubiquitination. By removing a 3 amino acid sequence from the receptor the ubiquitination of TrkA was reduced which resulted in an increase in TrkA protein levels and activity. In mice containing this mutation, the rise in TrkA activity was accompanied by enhanced thermal sensitivity and inflammatory pain. Anti-trkA (Cat. #AB-N03) was used at a concentration of 1:500 in immunohistochemistry.

J Immunol 192(1):245-258. doi: 10.4049/jimmunol.1302045 PMID: 24293631

Summary: Plasmodium falciparum is a protozoan parasite that can cause malaria in humans. The human malaria parasite reticulocyte –binding protein homolog 5 (PfRH5) is a potential target for neutralizing antibodies. PfRH5 binds basigin on erythrocytes, and through the use of anti-basigin (Cat. #AB-42), among other antibodies, the authors better characterized aspects of this binding that may be useful in preventing malaria.
