There is immense interest in the long-chain polyunsaturated fatty acids(LC-PUFAs) on account of their health-beneficial properties.There has been considerable interest in the production of LC-PUFAs in transgenic plants to provide a cheap,sustainable and clean source of these fatty acids.Several main LC-PUFAs,their roles and metabolic pathway in plant are introducedbriefly,progresses on biosynthesis of LC-PUFAs in transgenic plant are reviewed,and strategies for improving the yields of LC-PUFAs in plant are also discussed.

Many unusual fatty acids present in the seed oils of non-food plants are modified at the ?12 position either by the addition of epoxy or hydroxy groups or by the formation of triple (acetylenic) bonds or conjugated double bonds. The introduction of these functionalities into C18 fatty acids is catalyzed by a family of divergent forms of the fatty-acid ?12-desaturase (FAD2) enzyme. Genes encoding these enzymes have now been cloned from a variety of organisms and expressed in transgenic oilseeds. However,the accumulation of the intended fatty acids in transgenic plants has been relatively disappointing,and the mechanisms of these unusual fatty acids biosynthesis and transferring from phosphatidylcholine into storage triacylglycerols still need to be elucidated.

Objective To investgate role of TLR2 in the activation, the innate immune and inflammation of human platelets. Methods Human washed platelets were separated from healthy people(n=5) and were stimulated with different concentrations(1μg/ml, 5μg/ml, 10μg/ml) of TLR2 agonistPam3CSK4(a synthetic bacterial lipoproteins). Then the platelet aggregation rate, the expression of CD62p and TLR2 on the platelet surface were measured. Results The platelet aggregation rate were (28.32±5.67)%, (52.56±8.54)% and (76.24±11.23)%, respectively, at concentration of 1μg/ml, 5μg/mland 10μg/ml of Pam3CSK4, more than (12.83±2.43)% at 0μg/ml of it. In addition, the expression of CD62p were (18.45±2.66)%, (22.45±2.04)%, (29.53±4.08)%, respectively at above concentration of Pam3 CSK4, more than (11.20±1.67)% of CD62p at control group(P<0.01). The expression of TLR2 was not significantly increased at a lower concentration of Pam3CSK4(1μg/ml) with (16.85±6.10)% compared with(10.81±3.99)% at the control group. However, it were (21.15±9.90)% and (22.52±9.26)%, respectively, at a higher concentration(5μg/ml, 10μg/ml)more than(10.81±3.99)% at the control group(P<0.05). Conclusion Pam3CSK4 induce aggregation, activation and the up-regulation of TLR2 of platelet by stimulating TLR2 receptor of it. Thereafter, TLR2 play an important role in the innate immune of platelet.
