• lymphocytes
  • Therefore, determination of cytokine profiles in tonsil study will provide key information for further in-depth analysis of the cause and underlying mechanisms of these disorders, as well as the role and possible interactions between the T- and B-lymphocytes and other immunocompetent cells. (anatomic.us)
  • The lymphatic system produces immune cells called lymphocytes, which protect the body against disease and illnesses. (livestrong.com)
  • tissues
  • The palatine tonsil is one of the mucosa-associated lymphoid tissues (MALT), located at the entrance to the upper respiratory and gastrointestinal tracts to protect the body from the entry of exogenous material through mucosal sites. (wikipedia.org)
  • crypts
  • Palatine tonsils consist of approximately 15 crypts, which result in a large internal surface. (wikipedia.org)
  • Usually, tonsils are equal in size, pink in color, and covered with small deep depressions called crypts. (livestrong.com)
  • citation needed] The crypts extend through the full thickness of the tonsil reaching almost to its hemicapsule. (wikipedia.org)
  • In healthy tonsils the openings of the crypts are fissure-like, and the walls of the lumina are in apposition. (wikipedia.org)
  • A computerized three-dimensional reconstruction of the palatine tonsil crypt system showed that in the centre of the palatine tonsil are tightly packed ramified crypts that join with each other, while on the periphery there is a rather simple and sparse arrangement. (wikipedia.org)
  • furthermore, they can obstruct the normal flow of pus from the crypts, and may irritate the throat (people with tonsil stones may complain of the feeling that something is stuck in their throat). (wikipedia.org)
  • lymphoepithelial
  • Following clinical and histopathological examination, the diagnosis of reactive lymphoproliferative lesion, cystic lymphoepithelial lesion, and developmental lymphatic vessel malformation was reached. (hindawi.com)
  • citation needed
  • citation needed] Tonsil enlargement can affect speech, making it hypernasal and giving it the sound of velopharyngeal incompetence (when space in the mouth is not fully separated from the nose's air space). (wikipedia.org)
  • immune
  • These M cells then alert the underlying B cells and T cells in the tonsil that a pathogen is present and an immune response is stimulated. (wikipedia.org)
  • Altogether, therefore, several pieces of direct and indirect evidence indicate that the palatine tonsils are continuously engaged in local immune responses to microorganisms. (wikipedia.org)
  • Once this immunological impairment occurs, the tonsil is no longer able to function adequately in local protection nor can it appropriately reinforce the secretory immune system of the upper respiratory tract. (anatomic.us)
  • The main function of tonsils is to serve as the first line of defense in the immune system. (livestrong.com)
  • Tonsils play a role in the body's immune defense response to inhaled or ingested bacteria and viruses. (livestrong.com)

  • lumps
  • Tonsils only present as "white lumps" if they are inflamed or infected with symptoms of exudates (pus drainage) and severe swelling. (wikipedia.org)
  • human
  • It showed that human palatine tonsil is an active immunological organ containing a wide range of cytokine-producing cells. (anatomic.us)
  • Indeed, human tonsils persistently harbor microbial antigens even when the subject is asymptomatic of ongoing infection. (anatomic.us)
  • infections
  • As with any surgery, there are certain risks associated with tonsil removal, including various infections and bleeding. (mysurgeryabroad.com)
  • The physicians of the Texas Pediatric Surgical Associates support that tonsils are not capable of fighting the viral infections that children in urban environments are exposed to. (livestrong.com)
  • They say that tonsils were once effective in combating parasitic infections which are currently uncommon in developed counties. (livestrong.com)
