signaling amp-activated protein kinase (ampk), an energy sensing enzyme, has been implicated in controlling inflammation. in this study we investigated whether activation of ampk by metformin could protect the lung from lipopolysaccharide (lps)-induced acute injury by inhibitingng tlr4 pathway. male wistar rats were randomly divided into 3 groups (n=6): control group received normal saline (0.5...

Plasmodesmata (Pd) are plant intercellular connections that represent cytoplasmic conduits for a wide spectrum of cellular transport cargoes, from ions to house-keeping proteins to transcription factors and RNA silencing signals; furthermore, Pd are also utilized by most plant viruses for their spread between host cells. Despite this central role of Pd in the plant life cycle, their structural ...

  Proteases play a key role in protein digestion in ticks and other haematophagous insects. Our understanding of blood meal digestion in digestive system of ticks can be very useful for better understanding of basic rules for control of ticks. Cells of the midgut endocytose blood components. Blood proteins uptake by midgut cells, suggesting the presence of proteases in the midgut cells. In this...
