Physiology department faculty met with researchers and administrators at The Hamner Institutes for Health Sciences in RTP to learn about respective programs and begin discussions about possible new collaborations.
Our faculty represented the first group to meet following the establishment of a Memorandum of Understanding (MOU) between The Hamner and UNC schools of medicine, public health, and pharmacy as well as the Kenan-Flagler Business School.
The Hamner's focus on reproductive and developmental biology and respiratory biology aligns with the work of several faculty members here in Physiology. The Hamner has "adopted systems biology as a guiding research paradigm," which relates back to the fundamentals of physiology, as is described on their website:
In a sense, contemporary systems biology is a renaissance of physiology, a traditional integrative discipline. Biological research has enjoyed decades of success in dissecting the structures and functions of individual molecular and cellular components comprising an organism. However, the inherent complexity of biological systems, due not only to the large number of their constituents, but also to the intricate web of interactions between these constituents, have proven difficult to understand with reductionist approaches. Research has to be conducted at a more global, systems-level in order to gain understanding of the overall behavior of the biological networks that maintain normal physiology and the perturbations in these networks that lead to toxicity and disease.

Dr. Carlton Cuyler Hunt, professor emeritus of physiology, elected to
the American Academy of Arts and Sciences.
Dr. Hunt
led in the discovery and description of a system of neurons controlling the sensitivity and activity of the muscle stretch receptor (the vertebrate muscle spindle), which was a first indication that the central nervous system can control the activity that it receives from peripheral sense organs. Hunt's subsequent work on vibration reception by the Pacinian corpuscle and on the correlation between afferent fiber conduction velocity and afferent function are important landmarks in the development of insight into somatic sensory mechanisms.

Adrenomedullin signaling is necessary for murine lymphatic vascular development
Kimberly L. Fritz-Six, William P. Dunworth, Manyu Li and Kathleen M. Caron
[Full Text] [PDF] [Commentary]
|
|
| The lymphatic vascular system mediates fluid homeostasis, immune defense, and tumor metastasis. Only a handful of genes are known to affect the development of the lymphatic vasculature, and even fewer represent therapeutic targets for lymphatic diseases. Adrenomedullin (AM) is a multifunctional peptide vasodilator that transduces its effects through the calcitonin receptor–like receptor (calcrl) when the receptor is associated with a receptor activity–modifying protein (RAMP2). Here we report on the involvement of these genes in lymphangiogenesis... [Full Abstract] |

Crucial Role of Drosophila Neurexin in Proper Active Zone Apposition to Postsynaptic Densities, Synaptic Growth, and Synaptic Transmission
Jingjun Li, James Ashley, Vivian Budnik, and Manzoor A. Bhat
[Full Text] [PDF] [Supplemental Data] |
|
| Neurexins have been proposed to function as major mediators of the coordinated pre- and postsynaptic apposition. However, key evidence for this role in vivo has been lacking, particularly due to gene redundancy. Here, we have obtained null mutations in the single Drosophila neurexin gene ( dnrx ). dnrx loss of function prevents the normal proliferation of synaptic boutons at glutamatergic neuromuscular junctions, while dnrx gain of function in neurons has the opposite effect. DNRX mostly localizes to the active zone of presynaptic terminals. Conspicuously, dnrx null mutants display striking defects in synaptic ultrastructure, with the presence of detachments between pre- and postsynaptic membranes, abnormally long active zones, and increased number of T bars. These abnormalities result in corresponding alterations in synaptic transmission with reduced quantal content. Together, our results provide compelling evidence for an in vivo role of neurexins in the modulation of synaptic architecture and adhesive interactions between pre- and postsynaptic compartments. |
