Scientists say they've reversed brain aging with a simple nasal spray

The novel delivery method is less invasive than similar treatments in development and was shown in mice to effectively treat #glioblastoma by boosting the brain’s immune response.

Nose-shaping technology was at its height in the 1920s. But nasal Lamarckism kicked in, infants began to be born with acceptable noses, and within two generations nasal correction technology was first side-lined and then forgotten. We don't even have back-alley nose-modification clinics nowadays.

Comparative Characterization of #Bronchial and #Nasal #Mucus Reveals Key #Determinants of #Influenza A Virus #Inhibition http://biorxiv.org/cgi/content/short/2024.09.17.613498v1?rss=1

The ability of mucus to neutralize influenza A virus varies with the anatomical origin of the #airway cultures and correlates with the abundance of #triglycerides and sialylated #glycoproteins and #glycolipids.

A #OneHealth #Investigation into #H5N1 Avian #Influenza Virus #Epizootics on 2 Dairy #Farms, MedRxIV: https://www.medrxiv.org/content/10.1101/2024.07.27.24310982v1

We detected H5N1 HPAIV in 64% (9/14) of #milk specimens, 2.6% (1/39) of cattle #nasal swab #specimens, and none of 17 cattle #worker nasopharyngeal swab specimens... we detected #SARS-CoV-2 in a nasal swab from a sick #cow... 14.3% (2/14) of farm workers who donated #sera were recently symptomatic & had elevated neutralizing #antibodies against a related H5N1 strain.

#Cow “#Challenge” #Study Should Help Turn Tables on #H5N1 in Dairy #Herds, #USDA: https://www.ars.usda.gov/news-events/news/research-news/2024/cow-challenge-study-should-help-turn-tables-on-h5n1-in-dairy-herds/

In the first study, the #respiratory exposed #heifers became infected but showed minimal #clinical #signs of disease, limited to an increased but sporadic #nasal discharge 1 to 3 days after infection. Lesions were observed in one heifer 7 days after infection.

#Nasal #tissue-resident #memory #CD4+ T cells persist after #influenza A virus #infection and provide heterosubtypic #protection, BioRxIV, https://www.biorxiv.org/content/10.1101/2024.07.06.602325v1

Here, we find that, after IAV infection, antigen-specific CD4 TRM persist in the nasal tissue (NT) compartment and play a prime role in local viral clearance.

“The candidate, MPV/S-2P, uses a live-weakened version of a virus called murine pneumonia virus (MPV), which does not cause disease in humans.

MPV will deliver a stabilized version of the #spike protein, which the #SARSCoV2 virus, that causes #COVID19, uses to attach and infect human cells. This will teach the body to recognize the protein and train immune cells to attack if a person is infected.” #vaccine #COVIDvaccine #nasal https://bird.makeup/users/meetjess/statuses/1808464414053724252

#H9N2 #Influenza A Viruses Found to be #Enzootic in #Punjab #Pakistan's Bird #Markets with Evidence of #Human H9N2 #Nasal #Colonization, Int J Infect Dis.: https://www.ijidonline.com/article/S1201-9712(24)00217-0/fulltext

H9N2 IAV is likely enzootic in Punjab Province Pakistan's live bird markets and may be colonizing the noses of #workers and market visitors. Regular monitoring for avian influenza-associated human illness in Punjab seems to be a needed public measure.

Together, our study characterized the nasal #tropism of SARS-CoV-2 strains, immune #clearance, and #regeneration after infection. The shifting characteristics of viral infection at the #airway #portal provide insight into the variability of COVID-19 clinical features, particularly long COVID, and may suggest differing strategies for early local intervention.

Question for the #COVID19 Brains Trust.

Does anyone know what's happening with #nasal sprays for reducing transmission in Australia? I know the excellent Don Campbell at Northern Health is working on one, but not sure where it's up to.
Thanks!

Scientists at the Cambridge Institute of Therapeutic #Immunology and #Infectious Disease (CITIID) and Wellcome Sanger Institute showed that following #SARS-CoV-2 #infection, cells in the lining of the #lungs, #nasal cells, and immune #cells in the #blood show a blunted inflammatory response in obese patients, producing suboptimal levels of #molecules needed to fight the infection.
