1.NK subsets and the expression of C-myc and ras oncoproteins in lymphocytes and monocytes from patients with Behcet's syndrome
Chinese Journal of Pathophysiology 1989;0(05):-
The expression of C-myc, K-ras and H-ras oncoproteins in lymphocytesand monocytes, and NK subsets were studied in 21 patients with Behcet's syndrome (BS)and 40 healthy individuals. CD16~+,57~- cells of NK from BS patients were much decreasedwhen compared to the control. The positive percentages of three kinds of oncoprotein in BS lymphocytes and C-myc and K-ras oncoproteins in BS monocytes were significantly higher thanthat of the control. Positive correlations were found not only between C-myc expression oflymphocytes and serum ?-globulin%, IgM and IgG levels in BS, but also between C-mycexpression of monocytes and ESR. Expression of K-and H-ras oncoproteins in lympho-cytes and monocytes from BS patients were found to be negatively correlated with serumIgA level. Negative correlation was also found between C-myc expression in monocytesand CD16~+,57~- subset of NK. The significance of these results and the possible correlationsbetween BS and autoimmunity were discussed. It was suggeted that autoimmunity mightbe an important mechanism underlying BS.

Objective To investigate the mechanisms of methylglyoxal(MG)-induced injury of hippocam-pal neurons. Methods Primary cultured of hippocampal neurons from 1-day-old Sprague-Dawley rats were incuba-ted with MG for different time and dose period. Cells proliferation were assayed by methyl thiazolyl tetrazolium (MTT),and apoptosis was quantified by flow cytometer using annexin V-FITC and propidium iodide (PI) stai-ning. The protein and mRNA levels of brain-derived neurotrophie factor (BDNF) and tyrosine kinase B(TrkB) were assayed with Western Blotting and real-time PCR. Results Treatment with MG resulted in a concentration-dependent (r=0.946, P < 0.01) and time-dependent (r=0.993, P < 0.01) decreasing neurons viability. Com-pared with Oh group(1. 633±0. 153)%, 100 μM MG treatment for 2h,6h, 12h and 24h,the cellular apeptosis rate were significantly increased ((2. 833±0. 153)%, (3. 367±0. 153)%, (4. 433±0. 404)% and (8. 833± 0. 306)% respectivdy,all P<0.01). MG also increased the BDNF mRNA and protein expression after 12h treat-ment (P<0.05 or P<0.01),but decreased the TrkB mRNA and protein expression in the cells after 6h treatment (P<0.05 or P < 0.01). Conclusion MG has direct toxic effect on hippocampal neurons and can impaire the BD-NF-TrkB signal pathway by inhibiting the expression of TrkB,and increasing the apoptosis of hippocampal neurons.
