What is active and passive immunity? Explain the process of active and passive immunity and give one example. What is the purpose of humoral immunity? Describe the innate immune system. What is the role of antibodies in immunity? What are the different types of immunities? Give an example of...
Vaccines are designed to enable individuals to acquire immunity against infectious diseases by inducing the immune system to produce antibodies. Learn how the immune system and the vaccines work, and understand the definition, function, types,...

Much still remains elusive regarding the molecular mechanisms of orthohantavirus recognition by the innate immune response and viral antagonism within the reservoir host, however. This review provides a summary of the last 45years of research into orthohantavirus interaction with the host innate immune...
We found that in uninfected conditions, the resident immune cell population of the nasal mucosa decreases dramatically with age. We demonstrate that cell types are transcriptionally similar across the age range with no signs of differential activation that correlates with age. Finally, we take ...
Intact skin and mucosal barriers are crucial for the maintenance of tissue homeostasis as they protect host tissues from infections, environmental toxins, pollutants and allergens. A defective epithelial barrier has been demonstrated in allergic and autoimmune conditions such as asthma, atopic dermatitis,...
Cryptococcus neoformans, the causative agent of cryptococcosis, causes ~ 181,000 deaths annually, with males having a higher incidence of disease than females (7M:3F). The reason for this sex bias remains unclear. We hypothesized that this disparity w
This latter scenario would be similar to the situation in the yeast Saccharomyces cerevisiae, where there are two types of haploid cells, the alpha-cell and the a-cell, whose formation involves asymmetric cell divisions. The alpha-cell secretes the alpha-factor which binds to a specific receptor...
Some of those sphincters we can control voluntarily and others we can't. Are they all made up of the same type of muscle? If so, how do we explain that some are voluntary and others involuntary? Describe how and why both types of adaptive immunity can cause problems with ...
it is important for the infectious person, who could be asymptomatic, and any people near them, to wear face coverings, as masks significantly reduce the transmission of droplets depending on their types and how snuggly they’re worn. That is whyuniversal mask-wearingis important, even if ...
