A Vaccine for Asthma? #inmice | SciShow News

The video discusses allergic asthma, a condition affecting millions worldwide, and a new vaccine developed to combat it in mice. The vaccine targets cytokines IL4 and IL13, using conjugate technology to create a strong immune response. The study showed promising results in mice, with plans for human trials. Additionally, the video covers the recovery of the California condor, highlighting its genetic diversity and conservation efforts.

What is the primary cause of symptoms in allergic asthma?

• Immune response to allergens

• Bacterial infection

• Viral infection

• Lack of exercise

What is the role of IL4 and IL13 in allergic asthma?

• They are medications for asthma.

• They are proteins that trigger immune responses.

• They are types of bacteria.

• They are types of allergens.

How do conjugate vaccines work in the context of allergic asthma?

• They replace damaged lung cells.

• They neutralize cytokines to prevent immune responses.

• They increase the production of cytokines.

• They introduce allergens to the body.

What was the outcome of the vaccine tests on mice?

• Mice developed new allergies.

• Mice had less severe asthma symptoms.

• Mice showed no change in symptoms.

• Mice developed more severe symptoms.

What is a genetic bottleneck?

• A type of genetic mutation

• An increase in genetic diversity

• A decrease in population size leading to reduced genetic diversity

• A method of breeding animals

How did the genetic bottleneck affect the California condor?

• It increased harmful genes.

• It reduced genetic diversity but eliminated some harmful genes.

• It had no effect on the population.

• It caused the extinction of the species.

What is heterozygosity in genetic terms?

• Having identical alleles for a gene

• Having no alleles for a gene

• Having different alleles for a gene

• Having more than two alleles for a gene
