Innate recognition of infection in vertebrates can lead to the induction of adaptive immune responses through activation of dendritic cells (DCs). DCs are ... RE Sousa - 《Current Opinion in Immunology》 被引量: 705发表: 2004年 Mast cells in allergy and infection: Versatile effector and regulat...
They are the types of white blood cells that plays an important role in innate immune responses and injuries. They are characterized by specific granules in their cytoplasm which contains enzymes that protects from pathogens and fight infections. There are three types of granulocytes:neutrophils,eosino...
hyorhinis, which can be isolated from the healthy mucosal surfaces of the upper respiratory tract. In rare cases it can also cause arthritis and polyserositis. Since the innate immune system is an important first line of defense and promotes adaptive immune responses, we characterized the innate ...
Innate responses can also include inflammation and fever caused by humoral immunity - a component of innate immunity. If a pathogen passes this first barrier adaptive immunity takes over. Adaptive immunity, sometimes referred to as acquired immunity, occurs only after exposure to pathogens. This can...
Chemical barriers - Such chemical factors as the acidic conditions of the digestive tract create an unfavorable environment in which some invading microorganisms cannot survive.Cellular responses - Unlike other cells of the immune system, those of the innate immune system are non-specific. As such, ...
The differences in response to virus infection could not be explained by differences in the innate immune responses between the different types of ducks when examined at 2 days dpi, and earlier time points need to be evaluated. 展开 关键词: highly pathogenic avian influenza H5N1 type ducks ...
and their impact on the outcome of innate and adaptive responses. Most of these regulated cell death mechanisms have been classified as necrotic, proinflammatory cell death stimulating innate immune reactions. Activation of adaptive immunity, especially cytotoxic T cells by immunogenic cell death has als...
Different types of lymphocytes involved in immune responses are: T-cells or T- lymphocytes: ''T'' stands for thymus, the organ in which these cells mature. T-cells are involved in cell mediated immunity. B-cells also called B-lymphocytes: Here, the ''B'' stands for bone marrow, and ...
Figure 1. A framework of host immunological pathways against parasitic infections. The host immunological pathways can be divided into Tfh-mediated eradicable (IgG related) or Treg-mediated tolerable (IgA related) immune responses. For intracellular micro-organisms including intercellular protozoa, the er...
This makes innate immunity a good therapeutic target to limit the effects of adaptive immunity in transplant rejection [22]. The innate immune system is comprised of cellular components, such as macrophages, neutrophils, dendritic cells and natural killer cells, and blood proteins such as the ...
