They also rely on helper cells
and a linked picture.
Since the lung is related to the gut - both are exposed to the environment - we asked if natural helper cells
might also be in the lung and be important in asthma," said lead researcher Dr Dale Umetsu, from the Children's Hospital Boston.
IL-12 is known to shift T helper cell
response to a Th1 cytokine profile (Xu et al.
A specific subset of T helper cells
produces the cytokine interleukin 17 and is therefore called Th17 for short.

There was an increase in the percentage of naE[macron]ve T helper cells
, CD4+ cells, and a reduction in RNA viral load at several time points during the study.
We have identified the molecular switch that enables CD4 T cells to override their programming as helper cells
and transform into cytolytic (killer) cells," said La Jolla Institute scientist and study co-leader Hilde Cheroutre, Ph.
The researchers found that the helper cells
were all genetically engineered to recognize LCMV, a difference between mouse experiments and potential clinical application.
It appears that once HIV-exposed helper cells
are triggered to leave the blood, they are programmed to self-destruct," says Cloyd, who noted that about half of the HIV-infected CD4 cells entering the lymph nodes were destroyed in his experiments on mice.
CTL cells recognise and kill tumour or virally infected cells, Helper cells
recognise and secrete molecules to alert the immune system to the presence of a tumour or virally infected cell.
The helper cells
traveled up to 40 times their own length.
