Sleep is known to play a key role in facilitating various physiological processes, while also contributing to the healthy functioning of the brain. Lack of sleep and poor sleep quality have been linked to various chronic ...
Fasting, the voluntary abstention from eating and sometimes drinking for a set time, has become increasingly widespread, as some studies have found that it could boost the immune system and help prevent the development of ...
Medical investigators are theorizing that a combination of two treatments that activate myeloid cells may effectively treat a recalcitrant form of pancreatic cancer that thwarts conventional immunotherapy.
One of the more rigorous debates in immunology has centered on the origin of an enigmatic T cell population that possesses properties imparting memory and stem cell–like qualities, but facts about their genesis were so ...
Researchers at the Wuhan Sports University, China, have found a negative association between serum testosterone levels and arthritis. The relationship between serum testosterone and arthritis appeared nonlinear, and the finding ...
Aging is a natural process that affects all living organisms, prompting gradual changes in their behavior and abilities. Past studies have highlighted several physiological factors that can contribute to aging, including ...
Immunity is a biological term that describes a state of having sufficient biological defenses to avoid infection, disease, or other unwanted biological invasion. Immunity involves both specific and non-specific components. The non-specific components act either as barriers or as eliminators of wide range of pathogens irrespective of antigenic specificity. Other components of the immune system adapt themselves to each new disease encountered and are able to generate pathogen-specific immunity.
Adaptive immunity is often sub-divided into two major types depending on how the immunity was introduced. Naturally acquired immunity occurs through contact with a disease causing agent, when the contact was not deliberate, whereas artificially acquired immunity develops only through deliberate actions such as vaccination. Both naturally and artificially acquired immunity can be further subdivided depending on whether immunity is induced in the host or passively transferred from a immune host. Passive immunity is acquired through transfer of antibodies or activated T-cells from an immune host, and is short lived, usually lasts only a few months, whereas active immunity is induced in the host itself by antigen, and lasts much longer, sometimes life-long. The diagram below summarizes these divisions of immunity.
