Abstract
AIM Our study sought to identify dosimetric predictors of treatment-related lymphopenia during chemoradiotherapy for esophageal cancer. MATERIALS AND METHODS Patients with esophageal cancer who had received definitive chemoradiotherapy at our Institution were retrospectively assessed. The absolute volume of the spleen, body, and bone marrow that had received 5, 10, 20, and 30 Gy and the mean splenic dose were recorded. RESULTS Multivariate linear regression analysis revealed that docetaxel use and spleen dose-volume parameters (V5, V10, V20, V30, and mean splenic dose) were significant independent factors negatively influencing the absolute lymphocyte count at nadir. An increase of 1 Gy in mean splenic dose predicted a 2.9% decrease in nadir absolute lymphocyte count. Univariable logistic regression analysis showed that the mean splenic dose was a significant predictor of grade 4 lymphopenia. None of the body or bone marrow dose-volume parameters significantly predicted lymphopenia. CONCLUSION Higher spleen dose-volume parameters were associated with severe lymphopenia during chemoradiotherapy.

Abstract
The kinetics of recirculation of naive lymphocytes in the body has important implications for the speed at which local infections are detected and controlled by immune responses. With a help of a novel mathematical model, we analyze experimental data on migration of 51Cr-labeled thoracic duct lymphocytes (TDLs) via major lymphoid and nonlymphoid tissues of rats in the absence of systemic antigenic stimulation. We show that at any point of time, 95% of lymphocytes in the blood travel via capillaries in the lung or sinusoids of the liver and only 5% migrate to secondary lymphoid tissues such as lymph nodes, Peyer's patches, or the spleen. Interestingly, our analysis suggests that lymphocytes travel via lung capillaries and liver sinusoids at an extremely rapid rate with the average residence time in these tissues being less than 1 minute. The model also predicts a relatively short average residence time of TDLs in the spleen (2.5 hours) and a longer average residence time of TDLs in major lymph nodes and Peyer's patches (10 hours). Surprisingly, we find that the average residence time of lymphocytes is similar in lymph nodes draining the skin (subcutaneous LNs) or the gut (mesenteric LNs) or in Peyer's patches. Applying our model to an additional dataset on lymphocyte migration via resting and antigen-stimulated lymph nodes we find that enlargement of antigen-stimulated lymph nodes occurs mainly due to increased entrance rate of TDLs into the nodes and not due to decreased exit rate as has been suggested in some studies. Taken together, our analysis for the first time provides a comprehensive, systems view of recirculation kinetics of thoracic duct lymphocytes in the whole organism.

Abstract
The migratory behavior of antigen-presenting cells was investigated in vivo. Purified murine splenic dendritic cells and splenic and peritoneal macrophages were labelled and injected subcutaneously in the hind foot-pads of mice and monitored for seven days. In the first 24 h, a small quantity of label was recovered from popliteal but not inguinal lymph nodes with radioactive (111In-oxine and 3H-uridine) but not fluorescent (1,1'-dioctadecyl 3,3,3'3'-tetramethylindocarbocyanine perchlorate and fluorescein isothiocyanate) labelling of the antigen-presenting cells. Chemical fixation of the injected antigen-presenting cells had no effect on the detection of label in the popliteal lymph nodes, suggesting that it was unlikely to be due to active cellular migration. Label recovery from hind feet declined with time over the seven day period and was independent of the label type. Essentially the same observations were made whether the antigen-presenting cells were syngeneic or allogeneic to the injected mice and irrespective of the type of antigen-presenting cell used. However, allogeneic antigen-presenting cells, which did not migrate to the draining lymph nodes, successfully primed T lymphocytes in these lymph nodes as shown by a secondary in vitro mixed leukocyte reaction. Again, chemical fixation of the injected antigen-presenting cells had no effect on their ability to prime allogeneic T lymphocytes in the draining lymph nodes. These experiments suggest that, during experimental allo-sensitization via the subcutaneous route, indirect priming of allogeneic T lymphocytes may be a dominant pathway.

Abstract
Immunohistological analysis of sections prepared from human palatine tonsils revealed marked differences in the distribution of the adhesion molecule, leucocyte function antigen-1 (LFA-1) and its counter receptor, intercellular adhesion molecule-1 (ICAM-1). Light microscopy showed that LFA-1 was restricted to the leucocytes, particularly the lymphocytes. In contrast, staining of ICAM-1 was predominantly confined to the vascular endothelium with the greatest expression seen on the morphologically distinct high endothelial venules in the parafollicular areas; these are the sites that appear to support lymphocyte migration. Electron microscopy revealed that ICAM-1 was present on the luminal and lateral surfaces of the high endothelium and absent from the abluminal surface supported by basal lamina. The ICAM-1 was also absent from those surfaces of the endothelium that were in close contact with intravascular lymphocytes. Other cells stained by the anti-ICM-1 antibody included dendritic cells, plasma cells and epithelial cells in the reticulated crypt epithelium and in the upper strata of the non-keratinised stratified squamous epithelium. The high expression of LFA-1 was most prominent on lymphocytes, low on antigen-presenting cells and activated lymphoid cells, and not detectable on plasma cells, epithelial and endothelial cells. We propose that LFA-1/ICAM-1 binding participates in mediating the transendothelial migration of lymphocytes across the high endothelial venules of palatine tonsil.

Abstract
In experiments involving the collection of thoracic duct lymphocytes the anatomy of the abdominal thoracic duct in the rat has been further defined. In general, the abdominal thoracic duct lies posterior and to the left of the aorta between the renal arteries and the diaphragm. There are variations in the microsurgical approach to the classically described location of this organ that should be noted by investigators attempting to identify and dissect this structure.

Abstract
T and B cells continually migrate around the body by recirculating between blood and lymph via lymphoid tissues. This is an important way of fostering the cell-cell interactions required for the initiation of an immune response. Data from previous studies of T and B cell recirculation, based on relatively complex approaches, have been interpreted as evidence that the recirculation of B cells is more sluggish than for T cells. We have shown from a study in sheep that this is not the case. Lymphocyte migration through both the intestine and the prescapular lymph node was analyzed by cannulating efferent lymphatics. The lymph cells were labeled in vitro with Hoechst 33342, or other fluorochromes, then injected i.v., and the rate of their recirculation into the lymph was determined by fluorescence microscopy. A multicolor immunofluorescence assay was used to classify each recirculated cell as either a T or B cell. This established that the T and B cells from intestinal lymph and from prescapular lymph recirculate with similar kinetics. The recovery of i.v. injected T and B cells was the same in prescapular lymph, but fewer injected B cells than T cells were recovered in intestinal lymph. Thus, although the recirculation kinetics are the same for T and B cells, the two populations are handled differently in intestinal tissues and a lymph node remote from the gut.

Abstract
The introductory review amplifies the finding that simply holding lymphocytes in vitro reversibly compromises their ability to enter lymph nodes from the blood, although entry into the spleen is unaffected. The differential migration of T and B lymphocytes from the blood, lymphocyte traffic in athymic rats, and the secretion of a sulphated glycoconjugate by high endothelial cells in lymph nodes are also discussed. Original data are presented concerning the effects of varying the conditions under which lymphocytes are held in vitro (time, temperature, medium, centrifugation) on their ability to enter lymph nodes and also on their surface morphology. In general, conditions that reduced the number of microvilli and induced surface blebbing also tended to affect the delicate function of crossing specialized vascular endothelium; but there was no simple relationship between morphology and migratory behavior. The localization of lymphocytes to the bone marrow was augmented by holding them in vitro, and this effect was greater after holding at room temperature (RT) than at 0 degree C, in contrast to impaired entry into lymph nodes. Small amounts of heparin (10 units) injected along with lymphocytes significantly reduced early localization in lymph nodes. These findings have practical implications for the design of lymphocyte traffic experiments and are relevant to the mechanism of lymphocyte attachment to vascular endothelium, since the well-known effect of trypsinizing lymphocytes can be reproduced by maintenance in vitro.

Abstract
Aging NZB X SJL (NS) female mice provide a unique model of thymus pathology characterized by the intrathymic accumulation of large numbers of mature T and B cells. The purpose of the present work was to examine the possibility that this phenomenon results from the invasion of the thymus by cells from the periphery. Lymphoid cells labeled with chromium-51 or indium-111 were injected into syngeneic recipients to study their patterns of in vivo migration. Lymph node (LN) or spleen cells were found to localize significantly (1-2% of injected radioactivity) into the thymus of 12-month-old NS females but not into that of young recipients or of old NS males. However, intrathymic localization of injected LN cells was observed in castrated NS males which exhibit the same thymus pathology as NS females. Both radiolabeled T and B cells were found to enter the thymus of aged NS females but the latter cells about three times less efficiently than the former. Moreover, while thymocytes from young NS females were unable to recirculate to LN, those of old NS females showed increased LN-seeking capacity and part (1%) of them did migrate back into the thymus of old but not young NS females. In additional cell transfer experiments, the intrathymic migration of B cells into old NS females was further documented by using the antibody response to sheep erythrocytes as a tracer. Taken together, these observations indicate that the thymus of aging NS female mice is permeable to recirculating lymphocytes, suggesting that at least part of the mature T and B cells detected in this thymus are migrants from the periphery.

Abstract
The primary migration of lymphocytes from the blood was compared in nude rats and in euthymic rats. The flatter endothelium in the post-capillary venules (PCV) in the lymph nodes of nude rats was as efficient as the high endothelium of PCV in euthymic rats at capturing both T and B lymphocytes from the blood, although lymphocytes took a longer time to cross the PCV wall in nude recipients. The organ distribution of both lymphocytes and lymphoblasts ([125I]UdR-labelled cells) was broadly similar in nude and euthymic recipients. A second aim was to compare B and T lymphocytes with respect to the rate and sites at which they leave the blood after intravenous injection. As judged by sampling venous blood, B lymphocytes left the blood faster, but this was partly attributable to a larger intravascular pool of B lymphocytes in small blood vessels, especially in the lung. Thoracic duct lymphocytes from nude rats collected under standard conditions (16 h, O degrees C) entered the cervical lymph nodes very poorly, but when lymphocyte transfer was performed under more physiological conditions entry of B lymphocytes into lymph nodes was about half that of T lymphocytes. B lymphocytes did show a slight preference for entry into Peyer's patches compared with lymph nodes.
