Cigarette smoke-induced pulmonary emphysema in
Respiratory Research, 2005 Background Chronic obstructive pulmonary disease is associated with a chronic inflammatory response of the host to chronic exposure to inhaled toxic gases and particles. Although inflammatory cells of both the innate and adaptive immune system infiltrate

The Acquired Immune System [PDF]
Immunity, 2004 The invention of acquired immunity was like escalating a war with an omnipotent opponent, one that just deflects your energy or maybe even turns it back upon you. How does this knowledge affect the way we think about disease and immunity? For many years the study of immunology was carried out with little regard for infectious agents.

Innate and acquired humoral immunities to influenza virus are mediated by distinct arms of the immune system [PDF]
Proceedings of the National Academy of Sciences, 1999 "Natural" Igs, mainly IgM, comprise part of the innate immune system present in healthy individuals, including antigen-free mice. These Igs are thought to delay pathogenicity of infecting agents until antigen-induced high affinity Igs of all isotypes are

Opiates, immune system, acquired immunodeficiency syndrome, and nonhuman primate model [PDF]
Journal of Neurovirology, 2008 Both human immunodeficiency virus (HIV) and illicit drug addiction remain major health problems not only in the United States but all over globe. The effect of drug addiction on HIV/AIDS (acquired immunodeficiency syndrome) has been somewhat underexplored.

Variation in the innate and acquired arms of the immune system among five shorebird species [PDF]
Journal of Experimental Biology, 2006 SUMMARYTo contribute to an understanding of the evolutionary processes that shape variation in immune responses, we compared several components of the innate and acquired arms of the immune system in five related, but ecologically diverse, migratory shorebirds (ruff Philomachus pugnax L., ruddy turnstone Arenaria interpres L., bar-tailed godwit Limosa ...

Triiodothyronine suppresses humoral immunity but not T-cell-mediated immune response in incubating female eiders (Somateria mollissima) [PDF]
Gen. Comp. Endocrinol. 151 (2007) 188-194, 2007 Immunity is believed to share limited resources with other physiological functions and this may partly account for the fitness costs of reproduction. Previous studies have shown that the acquired immunity of female common eiders (Somateria mollissima) is suppressed during the incubation fast.

Gnawing Between Cells and Cells in the Immune System: Friend or Foe? A Review of Trogocytosis
Frontiers in Immunology, 2022 Trogocytosis occurs when one cell contacts and quickly nibbles another cell and is characterized by contact between living cells and rapid transfer of membrane fragments with functional integrity. Many immune cells are involved in this process, such as T
