En av de viktigste faktorene som påvirker utfallet av denne protokollen er bruk av frisk tonsill- materiale som utgangsmateriale. Derfor bør mandel prøvene behandles innen tre timer etter operasjonen. Mandlene kan fås fra både voksne og barn. Den tonsill- materiale fra barn vanligvis er mindre på grunn av den delvise kirurgisk fjerning av mandlene (tonsillotomy). Derfor er antall MNCer oppnådd fra tonsillotomy prøver (1 x 10 7 -1 x 10 8) er mindre i forhold til mandlene prøver (1 x 10 <sup...

Tonsils are collections of incompletely encapsulated lymphoid tissues that lie under, and in contact with, the epithelium in the upper aero-digestive tract. Usually the term &#8220;tonsils&#8221; refers to the palatine tonsils situated at the lateral walls of the oral part of the pharynx. The paired palatine tonsils together with the nasopharyngeal tonsil (adenoid), paired tubal tonsils and lingual tonsils constitute the so-called &#8220;Waldeyer&#180;s ring&#8221;. The latter is responsible for the initial contact between inhaled or ingested pathogens and the lymphoid tissues of the aerodigestive tract1,2. Indeed, numerous reports have shown that both bacterial and viral antigens can be detected in palatine tonsil tissue samples2-6.
The palatine tonsils are composed of dense lymphoid tissue covered by a stratified squamous non-keratinising epithelium. The tonsils have numerous crypts, epithelial invaginations, which penetrate the parenchyma increasing the surface area. Histologically, the palatine tonsils contain numerous lymphoid follicles with germinal centers, which are the sites for B cell maturation and differentiation (B-cell areas). Likewise, the palatine tonsils encompass T cells, which are mainly located in the extrafollicular regions (T-cell areas). In addition to the B and T cells, also various follicular dendritic cells can be detected in palatine tonsils1,2. 
Due to their anatomic location, the palatine tonsils are easily accessible by surgical interventions. For example, surgical removal of tonsils, known as tonsillectomy, is routinely carried out worldwide7. In children with tonsillar hyperplasia, a partial surgical removal of the tonsils (tonsillotomy) is sometimes used, causing less postoperative pain to the patients. Considering the accumulation of various pathogens in tonsils, surgically removed tonsils provide a unique opportunity to study the influence of viral and bacterial agents on tonsillar lymphocyte functions2,8. Furthermore it is possible to study if some pathogens prefer to reside in specific cell subpopulations9. In addition, as the tonsils are rich source of B lymphocytes, isolated tonsillar B lymphocytes can be efficiently used to study the activity of different B cell subpopulations10. However, as the palatine tonsils contain a mixture of cell types an efficient method to separate the different cell subpopulations is needed. 
Here, we describe a simple method for efficient and rapid isolation of tonsillar B and T cell populations from human palatine tonsils by using a magnetic-activated cell separation technique (Figure 1). The method described here is useful for scientists who want to assess the role of different infectious agents in human lymphoid organs such as palatine tonsils.

efficient isolation protocol for b and t lymphocytes from human palatine tonsils

Tonsils form a part of the immune system providing the first line of defense against inhaled pathogens. Usually the term &#8220;tonsils&#8221; refers to the palatine tonsils situated at the lateral walls of the oral part of the pharynx. Surgically removed palatine tonsils provide a convenient accessible source of B and T lymphocytes to study the interplay between foreign pathogens and the host immune system. This video protocol describes the dissection and processing of surgically removed human palatine tonsils, followed by the isolation of the individual B and T cell populations from the same tissue sample. We present a method, which efficiently separates tonsillar B and T lymphocytes using an antibody-dependent affinity protocol. Further, we use the method to demonstrate that human adenovirus infects specifically the tonsillar T cell fraction. The established protocol is generally applicable to efficiently and rapidly isolate tonsillar B and T cell populations to study the role of different types of pathogens in tonsillar immune responses.

En effektiv separasjon av tonsillare MNCs resulterer i høy-rene subpopulasjoner av B og T-lymfocytter. Dette ble bekreftet ved FACS-analyse ved bruk av anti-CD20 og anti-CD2 antistoffer for påvisning av B- og T-lymfocytt-populasjoner, respektivt (figur 3A). I motsetning til dette en ineffektiv separasjon av MNC resultater i cellefraksjoner som er en blanding av celler fra både B- og T-lymfocytt-subpopulasjoner (figur 3B).
