Whereas immune modulation has proven beneficial in multiple sclerosis (MS), we hypothesized that targeting down-stream modulators of neurogenesis and subsequent remyelination may offer an additional, if not superior, point of intervention in an attempt to repair damage and recover lost function. As such, the present study assessed the effectiveness of 30-day administration of the drug combination fluoxetine (5 mg/kg), simvastatin (1 mg/kg), and ascorbic acid (50 mg/kg) (FSA) on an early marker of neurogenesis, doublecortin (DCX), and functional recovery using the Montoya Staircase following lysolecithin-induced focal demyelination of the corpus callosum in middle-aged (10-11 month) male and female rats. Lysolecithin …

Proprioceptive sensory neurons encode critical mechanosensory information that helps determine how the body interacts with the outside world and monitors the proper execution of motor movements. Housed in skeletal muscles lie specialized mechanoreceptors that are critical to this feedback loop: muscle spindles supplied by group Ia & group II afferents, and Golgi tendon organs supplied by group Ib afferents relay information regarding changes in muscle force, length, and tension. All three afferent subtypes originate in the muscle and travel to the dorsal root ganglia, relaying information to the central nervous system. GTO and MS proprioceptive afferent subtypes have been identified, …
Potential Involvement Of Micro Vesicle Particles In The Synergistic Effects Of Ultraviolet-B Radiation And Platelet -Activating Factor Receptor Agonists On Cytokine Production, Shweta Bhadri

Cytokines play a pivotal role in regulating inflammation, which is a condition that makes the tissue vulnerable to different pathological and physiological conditions. Thus, how cytokines are regulated is an important area of study. Skin that receives ultraviolet B radiation (UVB), a major pro-oxidative stressor, results in the release of multiple cytokines and chemokines like tumor necrosis factor (TNF)-alpha and interleukin (IL)-8. Previous studies from our group and others have demonstrated synergistic release of TNF-alpha when UVB is combined with IL-1 or the lipid mediator Platelet-activating factor (PAF). Of interest, subcellular microvesicle particles (MVP) have been proposed to play an …

Ultraviolet (UV) radiation induces the formation of cyclobutane pyrimidine dimers (CPDs) in genomic DNA, which are normally removed by nucleotide excision repair. However, the fate of these adducts remain largely unexplored. Detection of these photoproducts in body fluids could act as a predictor of UV exposure and enable a better understanding of the pathogenesis of photosensitive skin diseases, such as lupus. Using cultured human keratinocytes exposed to UVB radiation in vitro, ultracentrifugation of cell culture supernatants, and immunodot blot analysis of isolated DNA, we have found that a small fraction of CPDs is released from cells in a dose- and …
