A phase of fast intracellular replication and spread (tachyzoite phase) stimulates immunity in the intermediate host, and this in turn induces parasite encystment in brain and muscle cells and lifelong persistence.
Niiya, F., Tatsumoto, T., Lee, K.S. & Miki, T. Phosphorylation of the cytokinesis regulator ECT2 at G2/M phase stimulates association of the mitotic kinase Plk1 and accumulation of GTP-bound RhoA.
The increased CO2 concentration in the gas phase stimulated the microalgal growth.
In addition, the dissolution of eutectic phase stimulated the probability of dynamic precipitation of β phase during deformation.
In the MN assay lymphocytes are irradiated in G0 phase, stimulated to divide, and micronuclei are scored in binucleate cells resulting from cytokinesis block.
Switching to fresh medium (controls) in late exponential phase stimulated growth, and switching to N-free medium (N deprivation, -N) induced an intermediate response; slightly lower growth than in the controls, but higher than that of the standard continuous cultures.
While the authors qualify their finding by stating that it cannot be excluded that the transferred Th2 cells at some stage were entering follicles and expressing CXCR5 25, the experiments are a strong indication that committed Th2 cells in the extrafollicular phase stimulate pre-GC B cells.
Notably, phosphorylation of B-Myb by Cyclin A/cyclin-dependent kinase 2 (Cdk2) at the onset of S-phase stimulates its transactivation potential by relieving repressive effects exerted by its C-terminal domain.
Patients and controls were examined in the ovulation and pre-menstrual phases, stimulating in random order the hand and facial zone.
However, the marked gas phase-stimulated CGRP release from the isolated trachea does not correspond with the minor sensory irritancy that is reported from Cambridge-filtered CS inhaled by humans (18).
