Animal personalities and their implications for complex signaling

引用

Current Zoology 2014年第3期60卷 381-386页

作者： Nicholas DIRIENZO Ann V HEDRICK Department of neurobiology Physiology & Behavior Animal Behavior Graduate Group University of California Davis CA 95616 USA Department of neurobiology Physiology & Behavior University of California Davis CA 95616 USA

Animal personalities have been a major focus of behavioral ecology over the past decade. Consistent individual dif ferences in behavior have been found across taxa, and have been shown to influence a range of ecological processes. The role of personalities in sexual selection has been considered, and examples exist that show selection for personality traits with both assortative and disassortative mating patterns between personality types. One overlooked aspect of the personality and sexual se lection literature is the potential for personalitysignaling interactions, specifically with complex signaling. Complex signaling is a diverse topic in itself, and in short, consists of multiple signals within one or more modalities that interact to elicit a receiver response. Research into complex signaling has been thorough, although at times studies discover complex signaling systems that fail to fit into one of the existing hypotheses in the literature. Here, we argue that personalities may interact with complex signal ing, which should be considered by researchers of both personality and sexual selection and communication. We describe several ways in which personalitycomplex signaling interactions could affect both the signaler and receiver, and the way in which they may drive personalityspecific signals as well as receiver preferences. Finally, we discuss how considering personality in com plex signaling studies may inform theory as well as improve the ability of researchers to accurately describe its function.

Mesenchymal stem cell therapy for retinal ganglion cell neuroprotection and axon regeneration

Neural Regeneration Research 2015年第3期10卷 371-373页

作者： Ben Mead Ben A.Scheven Neurotrauma Research group Neurobiology SectionSchool of Clinical and Experimental MedicineUniversity of Birmingham School of Dentistry University of Birmingham

Retinal ganglion cells （RGCs） are responsible for propagat- ing signals derived from visual stimuli in the eye to the brain, along their axons within the optic nerve to the superior colliculus, lateral geniculate nucleus and visu- al cortex of the brain. Damage to the optic nerve either through trauma, such as head injury, or degenerative dis- ease, such as glaucoma causes irreversible loss of function through degeneration of non-regenerating RGC axons and death of irreplaceable RGCs, ultimately leading to blindness （Berry et al., 2008）. The degeneration of RGCs and their axons is due to the loss of the necessary source of retrogradely transported neurotrophic factors （NTFs） being hindered by axonal injury. NTFs are survival factors for neurons and play a pivotal part in axon regeneration. Stem cells particularly mesenchymal stem cells （MSCs） have been shown to possess a natural intrinsic capacity for paracrine support, releasing multiple signalling mol- ecules including NTFs. By transplanting MSCs into the vitreous, they are positioned adjacent to the injured reti- na to provide paracrine-mediated therapy for the retinal neuronal cells （Johnson et al., 2010a; Mead et al., 2013）. Additionally, MSCs may be pre-differentiated into sup- portive glial-like cells, such as Schwann cells, which could further increase their potential for paracrine support of injured neurons （Martens et al., 2013）. Thus, MSCs have received considerable attention as a new cellular therapy for both traumatic and degenerative eye disease, acting as an alternative source of NTFs, protecting injured RGCs and promoting regeneration of their axons （Figure 1）.
