A friendly foe -- Bacteria residing in the gut boost immune response to tumors
... from the gut to the lymph nodes, where the immune response
to their presence increased the activation of tumor-specific CD8+ T cells and resulted in tumor regression. This effect was found to involve toll-like receptor 4. Conversely, a reduction in the number of host microorganisms by the use of antibiotics ...

...he VA, will examine the role that hormones play in response
to alcohol withdrawal, include the possibility that the male hormone androgen exacerbates cell death in males. "What we're looking at now is the involvement of testosterone in mediating the cell death in females," Wiren said. "Not just in chronic c...
Humboldt squid on the move

to a localizedwarming of the ocean. Zeidberg and Robison suggest that Humboldt squid populations may be growing and expanding northward due to a decrease in the number of predators and competitors in their home range (the Equatorial Pacific). Chie...

from the central as well as the peripheral process of a dorsal root ganglion (DRG) neuron. This conditioning effect is mediated by altered transcription of multiple genes and involves both enhanced axonal growth and reduced inhibition by myelin. Seij...
