The following are few links I received Dec. 08 from my yahoo news
alert using the keyword asthma, so perhaps there is hope in the near
future for us asthmatics.
Lets just hope so.

To determine whether immunostimulatory sequences of DNA (ISS) can reverse
established airway remodeling, mice that had developed airway remodeling
following 3 mo of repetitive OVA challenges, were treated with ISS for 1-3
mo. Systemic administration of ISS to mice that had already developed
established airway remodeling significantly reduced the degree of airway
collagen deposition (assessed by lung collagen content, peribronchial
trichrome staining, and immunostaining with anticollagen type III and type V
Abs). ISS reduced bronchoalveolar lavage and lung levels of TGF-1 and
reduced the number of TGF-1-positive eosinophils and TGF-1-positive
mononuclear cells recruited to the airway. In vitro studies demonstrated
that ISS inhibited TGF-1 expression by macrophages (RAW 264.7 cell line and
bone marrow-derived macrophages). In addition, ISS significantly reduces
lung levels of expression of the chemokine thymus- and activation-regulated
chemokine, as well as the number of peribronchial CD4+ lymphocytes that
express Th2 cytokines that promote peribronchial fibrosis. Overall, these
studies demonstrate that ISS can reverse features of airway collagen
deposition by reducing levels of lung TGF-1, as well as by reducing levels
of the chemokine thymus- and activation-regulated chemokine and the numbers
of peribronchial CD4+ lymphocytes that drive the ongoing Th2 immune
response.

To determine whether inhaled immunostimulatory DNA sequence oligonucleotides
containing CpG motifs mitigate the pathophysiologic manifestation of the
asthmatic phenotype (airways hyperresponsiveness and airways remodeling),
rhesus monkeys with experimentally induced allergic airways disease were
treated seven times with inhaled immunostimulatory oligonucleotides (or
sham) periodically for 33 weeks. Airways hyperresponsiveness was reduced
twofold in immunostimulatory DNA sequence-treated compared with sham-treated
monkeys. Airways from immunostimulatory oligonucleotide-treated monkeys had
thinner reticular basement membranes, fewer mucous cells, fewer eosinophils,
and fewer mast cells than sham-treated allergic monkeys. We conclude that
inhaled immunostimulatory oligonucleotides can attenuate the magnitude of
airway hyperreactivity and airways remodeling produced in nonhuman primates
with experimentally induced allergic airways disease.
