Autophagy Is a Defense Mechanism Inhibiting Invasion and Inflammation During High-Virulent Haemophilus parasuis Infection in PK-15 Cells
In this study, we sought to investigate whether SH0165 (serovar 5, high-virulent strain) and HN0001 (serovar 6, non-virulent strain) infection induces autophagy and the specific role of autophagy in bacterial invasion and inflammation during H. parasuis infection. Moreover, we explored the mechanism underlying autophagy regulated inflammation through inflammatory signaling cascades during H. parasuis infection. This observation could provide useful information for further understanding the role of autophagy in H. parasuis infection and improve our knowledge of new strategies against this pathogen. Materials and Methods B...

SOCS and Herpesviruses, With Emphasis on Cytomegalovirus Retinitis
Christine I. Alston1,2 and Richard D. Dix1,2* 1Department of Biology, Viral Immunology Center, Georgia State University, Atlanta, GA, United States 2Department of Ophthalmology, Emory University School of Medicine, Atlanta, GA, United States Suppressor of cytokine signaling (SOCS) proteins provide selective negative feedback to prevent pathogeneses caused by overstimulation of the immune system. Of the eight known SOCS proteins, SOCS1 and SOCS3 are the best studied, and systemic deletion of either gene causes early lethality in mice. Many viruses, including herpesviruses such as herpes simplex virus and cytomega...

The Functions of Non-coding RNAs in rRNA Regulation
Qi Yan1, Chengming Zhu1, Shouhong Guang1,2* and Xuezhu Feng1* 1Hefei National Laboratory for Physical Sciences at the Microscale, School of Life Sciences, University of Science and Technology of China, Hefei, China 2CAS Center for Excellence in Molecular Cell Science, Chinese Academy of Sciences, Hefei, China Ribosomes are ribonucleoprotein machines that decode the genetic information embedded in mRNAs into polypeptides. Ribosome biogenesis is tightly coordinated and controlled from the transcription of pre-rRNAs to the assembly of ribosomes. Defects or disorders in rRNA production result in a number of human ri...
