Background In the animal combined and Human study, we have previously found that treatment of 5-day increase the plasticity of cortical also facilitates brain – derived neurotrophic factor ( BDNF ) – receptor tyrosine kinase B (TrkB) signaling and increased activated TrkB and N-methyl-d-aspartate receptor (NMDAR) association in both the cortex and peripheral lymphocytes.
Patients with Parkinson’s disease (PD), in general, show decreased cortical plasticity, as shown by electrophysiological and behavioral studies. Here, we tested the hypothesis that exercise programs that improve motor function and appears to slow the progression of symptoms can improve BDNF -TrkB signals in lymphocytes. Methods A total of 16 patients with PD experience 4 -week intensive multidisciplinary rehabilitation treatment (MIRT), which includes aerobic exercise and physical and occupational therapy.
Blood was collected before and after 2 and 4 MIRT week. Lymphocytes isolated to check the BDNF -TrkB signaling caused by incubation with recombinant Human BDNF . TrkB signaling complex, extracellular-signal-regulated kinase-2 and protein-kinase-B immunoprecipitated; immunocomplexes contents determined by Western blotting. Results After MIRT, all patients showed improvements in motor function. TrkB interaction with NMDAR and BDNF -TrkB signaling increases in peripheral lymphocyte receptor, intracellular mediators, and the downstream level.
The decrements in the Unified Parkinson’s Disease Rating Scale II (UPDRSII) and total scores were significantly correlated with the increase in receptor TrkB signaling, intracellular mediators, and the level of interaction of NMDAR. Conclusion The significant correlation between reduced UPDRS score and change the activity of lymphocytes demonstrated that improved BDNF -TrkB signaling in lymphocytes and reduce the severity of symptoms of PD may be related.

Late pulses like receptor 4 inversely attenuating the effects of Chinese herbal Xiao-Qing-Long-Tang on allergen-induced nerve growth factor and thymic stromal lymphopoietin.4
Xiao-Qing-Long-Tang (XQLT) is known to regulate the immune allergic reaction. The purpose of this study was to investigate the effects of XQLT on allergen-induced cytokine and related signaling pathways. A rat model of acute allergic used to investigate the effects of XQLT on nerve growth factor (NGF) during an allergic reaction, while Human pulmonary alveolar epithelial cells (HPAEpiCs) was used to investigate the effects of XQLT on Dermatophagoides pteronyssinus group 2 ( der p 2) -induced NGF, p75 neurotrophin receptor (p75NTR) and thymic stromal lymphopoietin (TSLP) expression. XQLT shown to inhibit allergic reactions associated NGF- and p75NTR in a mouse model.
XQLT also reduce the expression of Toll-like receptor 4 (TLR 4 ) in the lungs of rat models. XQLT inhibit Der p 2-induced NGF, TSLP and p75NTR expression in cell lines HPAEpiC. The use recombinant TLR soluble 4 (sTLR 4 ) in the competitive test XQLT partially attenuated inhibitory effect on NGF, TSLP and p75NTR expression in HPAEpiC cells. XQLT inhibitory effect on Ser536 phosphorylation of p65 (nuclear factor-kB; NF-kB), a TLR 4 the impact factor, is also attenuated by sTLR 4 .

In conclusion, XQLT hampered Der p allergen-induced NGF, p75NTR and TSLP expression. This inhibition is attenuated by sTLR 4 . The working mechanism of XQLT may be correlated with TLR 4 , the main receptors in the innate immune system. The findings of this study can focus on the pharmacological target search XQLT to TLR 4 , which is important in the presentation of allergens path.
