Hepatitis B virus X increases immune cell recruitment by induction of chemokine SDF-1.

abstract：:This study investigates to what extent the expression of the slow myosin heavy chain (MyHCI) isoform and the slow type sarcoplasmic reticulum Ca2+ ATPase (SERCA2a) isoform are co-regulated in fibers of regenerating skeletal soleus muscle.
