The Immune System: The phrase 'three lines of defense' can be thought of in the military sense, where the first stage is to completely shut out an invasion (infection); then, if an invasion occurs, send agents to investigate, mitigate and/or deal wit...
Most are detected and destroyed within minutes or hours by defense mechanisms that do not rely on the clonal expansion of antigen-specific lymphocytes. These are the mechanisms of innate immunity. To recognize pathogens, both the innate and adaptive immune systems can distinguish between self and ...
Your immune system protects your most important resource: you! And its defenses are formidable: harmful invaders like bacteria, viruses, or parasites have to get through several complex layers of protection to do their damage. Not only do they have to br
57). Because specific immune reactions prevent or terminate cryptosporidiosis, passive immunization strategies for control of the disease in neonatal and immunodeficient hosts have been investigated (examined in referrals 8 and 35). In such hosts, suboptimal active immune reactions increase susceptibility ...

1a). Y476 was immune to specific isolates of Magnaporthe oryzae (M. oryzae), and its salt tolerance was better than that of the cultivated rice variety Nipponbare (Nip) (Fig. 1b, c). Fig. 1: Morphology, rice blast resistance and salt tolerance of the O. rufipogon accession Y476. a ...
Among these proteins, 26% were related to energy regulation, 15% to protein destination and storage, 11% to defense against disease, 11% to metabolism, 9% to protein synthesis, 4% to secondary metabolism, and 24% were of unknown function. Our study provides important information on the use...

Cytokines produced in HL, either by RS or infiltrating cells, might explain the presence and maintenance of an impaired immune response. Chemokines (cytokines with chemoattractant properties) produced by RS cells play a major role in leukocyte trafficking. These molecules with specific receptor ...
