Book Description
Lymphocytes constantly survey the lymph nodes in search for potential infection by a pathogen. They enter the afferent lymphatic vessel that serves as a conduit to transport the motile lymphocytes to the draining lymph node. Lymphatic vessels (LVs) are present in most vascularized tissues. They are traditionally regarded as passive conduits for soluble antigens and leukocytes. Afferent LVs begin as blind ended capillaries, which give rise to collecting vessels that merge and connect with draining lymph nodes (dLNs). Initial lymphatic capillaries are composed of Lymphatic Endothelial Cells (LECs) connected by discontinuous cell junctions, which join to form larger collecting lymphatic vessels, and ultimately feed into the LN subcapsular sinus. Within the LN, LECs are localized to the subcapsular, cortical, and medullary sinuses, where they interact with incoming and exiting leukocytes. LECs, and in general LN stromal cells, have emerged in the recent years as active players in the immune response. In support to this,studies have shown that the immune response generated during inflammation and under pathologic conditions is accompanied by modeling of the LVs and generation of new lymphatics, a process known as lymphangiogenesis. These facts strongly suggest that LECs and stromal LN cells in general, are not inert players but rather are part of the immune response by organizing immune cells movement, exchanging information and supplying survival factors. The purpose of this research topic is to review the role of the LECs during immune homeostasis and cancer. Considering the critical role of lymphangiogenesis in many pathologies like chronic and acute inflammation, autoimmunity, wound healing, graft rejection, and tumor metastasis, it is important to understand the molecular mechanisms that govern the cross talks between the LECs and immune cells during homeostasis and inflammation.

Book Description
This volume examines in detail the role of chronic inflammatory processes in the development of several types of cancer. Leading experts describe the latest results of molecular and cellular research on infection, cancer-related inflammation and tumorigenesis. Further, the clinical significance of these findings in preventing cancer progression and approaches to treating the diseases are discussed. Individual chapters cover cancer of the lung, colon, breast, brain, head and neck, pancreas, prostate, bladder, kidney, liver, cervix and skin as well as gastric cancer, sarcoma, lymphoma, leukemia and multiple myeloma.

Book Description
This volume explores the various methods used to study tertiary lymphoid structures (TLS) in pathological situations. Pre-clinical models are also discussed in detail to show how TLS structure, development, and maintenance can be targeted and studied in vivo. The chapters in this book cover topics such as humans and mice; strategies to quantify TLS in order to use it in stained tissue sections; classifying a gene signature form fixed and paraffin-embedded tissues; and development of murine inflammatory models to help look at TLS in the context of infection or malignancy. Written in the highly successful Methods in Molecular Biology series format, chapters include introductions to their respective topics, lists of the necessary materials and reagents, step-by-step, readily reproducible laboratory protocols, and tips on troubleshooting and avoiding known pitfalls. Authoritative and thorough, Tertiary Lymphoid Structures: Methods and Protocols is a valuable resource that increases the reader’s knowledge on immune functions and how they will pave the way to future therapeutic applications.

Book Description
This manual lymph drainage guide covers the anatomy, physiology, and pathophysiology of the lymphatic system, providing key background information necessary for effective treatment. Chapters are structured according to anatomic regions, focusing on the lymphatic knots and their tributary regions in the throat, armpit, trunk, and groin. Photographs illustrate the lymphatic knots and lymphatic courses, which are drawn on the human body, and provide a clear picture of the structures to be treated. Designated points are numbered to illustrate the progression of treatment in each region. Also includes coverage of complete decongestive therapy (CDT). Explains procedures in a detailed, step-by-step format. Features a helpful chart of lymph node groups and their tributary regions that outlines each lymph node as it pertains to a specific anatomical region. Key information is summarized in the margins, making it easier for readers to review what they've read and focus on important topics. Self-test questions provide an excellent means for readers to assess their comprehension and review key material in the book. These questions are also helpful in preparing for exams. Two-color illustrations help the reader visualize and learn theoretical aspects of this therapy. The text has been completely updated to reflect the latest techniques in lymph drainage therapy. Coverage of individual treatment strokes and stroke sequences have been updated, with more comprehensive descriptions and detailed photos that illustrate proper hand placement, pressure, and movement. Expanded coverage of complete decongestive therapy, including a CDT survey — consisting of the case history, examination, and palpation — that can be used to gather valuable information to formulate therapeutic goals and evaluate treatment results.

Book Description
The immune system employs TLOs to elicit highly localized and forceful responses to unresolvable peripheral tissue inflammation. Current data indicate that TLOs are protective but they may also lead to collateral tissue injury and serve as nesting places to generate autoreactive lymphocytes. A better comprehension of these powerhouses of disease immunity will likely facilitate development to unprecedented and specific therapies to fight chronic inflammatory diseases.
