Garth L Nicolson, Michael E Ash
Membrane Lipid Replacement is the use of functional, oral supplements containing mixtures of cell membrane glycerolphospholipids, plus fructooligosaccharides (for protection against oxidative, bile acid and enzymatic damage) and antioxidants, in order to safely replace damaged, oxidized, membrane phospholipids and restore membrane, organelle, cellular and organ function. Defects in cellular and intracellular membranes are characteristic of all chronic medical conditions, including cancer, and normal processes, such as aging...

There are many factors that can influence the pharmacokinetics (PK) of a mAb or Fc-fusion molecule with the primary determinant being FcRn-mediated recycling. Through Fab or Fc engineering, IgG-FcRn interaction can be used to generate a variety of therapeutic antibodies with significantly enhanced half-life or ability to remove unwanted antigen from circulation. Glycosylation of a mAb or Fc-fusion protein can have a significant impact on the PK of these molecules. mAb charge can be important and variants with pI values of 1-2 unit difference are likely to impact PK with lower pI values being favorable for a longer half-life...

OBJECTIVE: The contralateral limbs of patients with unilateral lymphedema in the lower limbs (LLs) can exhibit abnormal lymphatic circulation, even in the absence of lymphedema. This idea is based on a number of reports that have studied isolated cases using lymphoscintigraphy. It is likely that these patients previously had some form of lymphopathy, and the lymphedema arose after the action of some external factor. However, there are no studies in the literature that adequately assess the asymptomatic contralateral limbs of these patients or address the prevalence and characteristics of the abnormal lymphatic circulation in these limbs...

BACKGROUND: Cancer is a mosaic of tumor cell subpopulations, where only a minority is responsible for disease recurrence and cancer invasiveness. We focused on one of the most aggressive circulating tumor cells (CTCs) which, from the primitive tumor, spreads to the central nervous system (CNS), evaluating the expression of prognostic and putative cancer stem cell markers in breast cancer (BC) leptomeningeal metastasis (LM). METHODS: Flow cytometry immunophenotypic analysis of cerebrospinal fluid (CSF) samples (4...

OBJECTIVE: The purpose of this study was to assess blood flow after manual lymphatic drainage (MLD) in women who had received surgery for breast cancer and had post-axillary lymphadenectomy lymphedema. METHODS: Sixteen volunteers (mean age 64 ± 11.44 years) were divided into 2 groups. Those in group 1 received MLD without upper limb elevation, and those in group 2 received MLD with elevation of 30° of the upper limb. Blood flow velocity of the brachial vein and artery were measured using Doppler ultrasound before, immediately after, and 30 minutes after MLD, with and without 30° of upper limb elevation as defined by a random crossover design and an interval (washout) of 7 days...

The human central nervous system and its vascularity has evolved a complex yet useful barricade, called the blood-brain barrier. The understanding of this barrier and the transport proteins that allow a selective access across it remains fundamental in designing chemicals and molecules that could cross it and prove therapeutically beneficial. After the recent findings of the brain-lymphatic link and the movement of chemical molecules from the central nervous system into general circulation, the model of the blood-brain barrier needs to be revisited...

PURPOSE OF REVIEW: The central nervous system (CNS) has a unique relationship with the immune system. This review highlights the distinct roles of lymphatic vessels and endothelial cells in the interface between CNS and immune cells and invites to revisit the concept of CNS immune privilege. RECENT FINDINGS: T cells can follow several routes to penetrate the CNS parenchyma but may also benefit, together with antigen-loaded presenting cells, from the newly described lymphatic network to exit the CNS...

The objective ot this study was to investigate whether lymphatic markers measured in women during the second trimester are associated with critical congenital heart defects (CCHDs) in offspring. This is a retrospective cohort study of pregnant women who participated in the California Prenatal Screening Program. CCHD data in the offspring was captured by linking birth certificate data with hospital patient discharge records. Second trimester samples were assayed for vascular endothelial growth factor (VEGF), platelet derived growth factor (PDGF) AA/BB, and PDGF AB...

BACKGROUND: ZFAS1 is a newly identified long noncoding RNA (lncRNA) that promotes tumor growth and metastasis. Exosomes mediate cellular communications in cancer by transmitting active molecules. The presence of ZFAS1 in the circulating exosomes and the roles of exosomal ZFAS1 in gastric cancer (GC) remains unknown. The aim of this study was to investigate the potential roles of exosomal ZFAS1 in GC. METHODS: The expression of ZFAS1 was examined in the tumor tissues, serum samples, serum exosomes of GC patients and cell lines using qRT-PCR...

Mesenteric lymph is vital for immune cell trafficking and intestinal fluid and chyle transport, which aid homeostatic maintenance. There have been few reports investigating the profiles and circulatory dynamics of mesenteric lymph microRNAs (miRNAs). The present study aimed to provide a comprehensive analysis of miRNAs in normal rodent mesenteric lymph. Reverse transcription‑quantitative polymerase chain reaction (RT‑qPCR)‑based array analysis was performed to examine the expression levels of 375 miRNAs in normal rat mesenteric lymph...

Herbivores employ numerous strategies to reduce their exposure to toxic plant secondary chemicals (PSCs). However, the physiological mechanisms of PSC absorption have not been extensively explored. In particular, the absorption of PSCs via intestinal lymphatic absorption has been largely overlooked in herbivores, even though this pathway is well recognized for pharmaceutical uptake. Here, we investigated for the first time whether PSCs might be absorbed by lymphatic transport. We fed woodrats (Neotoma albigula) diets with increasing concentrations of terpene-rich juniper (Juniperus monosperma) either with or without a compound that blocks intestinal lymphatic absorption (Pluronic L-81)...

BACKGROUND: Lymphatic filariasis (LF) is a debilitating disease associated with extensive disfigurement and is one of a diverse group of diseases referred to as neglected tropical diseases (NTDs) which mainly occur among the poorest populations. In line with global recommendations to eliminate LF, Kenya launched its LF elimination programme in 2002 with the aim to implement annual mass drug administration (MDA) in order to interrupt LF transmission. However, the programme faced financial and administrative challenges over the years such that sustained annual MDA was not possible...

Professional antigen-presenting cells (APCs) in the skin include dendritic cells, monocytes, and macrophages. They are highly dynamic, with the capacity to enter skin from the peripheral circulation, patrol within tissue, and migrate through lymphatics to draining lymph nodes. Skin APCs are endowed with antigen sensing, processing, and presenting machinery and play key roles in initiating, modulating, and resolving cutaneous inflammation. Skin APCs are a highly heterogeneous population with functionally specialized subsets that are developmentally imprinted and modulated by local tissue microenvironmental and inflammatory cues...

Failing Fontan continues to be major problem for patients on the univentricular pathway. Failing Fontan is often complicated by chylothorax, plastic bronchitis and protein loosing enteropathy. The role of lymphatic circulation in Fontan circulation is still being researched. Newer imaging modalities give insight into the role of abnormal dilatation and retrograde flow in lymphatic channels post Fontan. Interventional strategies targeting abnormal lymphatic channels, provides an alternative management strategy for patients with failing Fontan...

To identify specific circulating microRNAs that were associated with the lymphatic metastasis in lung cancer, we performed miRNA microarray analysis of lymph node with and without metastasis from five lung cancer patients. Top six differentially expressed miRNAs were selected for further validation. A training cohort of 26 patients with lung cancer was firstly recruited and the selected miRNAs in the plasma samples were investigated. miRNA-422a, with highest diagnostic accuracy in lymphatic metastasis was identified (AUC, area under the receiver operating characteristic curve, 0...

BACKGROUND: The increases in capillary wall permeability and capillary hydrostatic pressure are considered to be the causes for the acute swelling seen in flaps; however, disruption of the circulating flap lymphatics could be another contributory factor. In this study we monitor the development of flap edema in a series of 18 prefabricated flaps and aim to delineate the natural history of this phenomenon by use of lymphography. METHODS: Postoperative swelling was monitored in a series of 18 pre-expanded prefabricated cervical skin flaps used for hemi-facial burns-scar resurfacing...

Repeated binge-like alcohol intoxication (RBAI) induces whole-body insulin resistance, which is predicted to increase the risk for metabolic syndrome and type 2 diabetes. Previously we showed that acute alcohol intoxication increases mesenteric lymphatic permeability, perilymphatic adipose tissue (PLAT) inflammation, and circulating lipopolysaccharide (LPS) levels in rats. We hypothesize that mesenteric lymphatic hyperpermeability, adipose tissue inflammation and associated dysregulated adipokine expression and insulin signaling are central mechanisms underlying whole body metabolic dysregulation resulting from RBAI...

Vera P Krymskaya, Francis X McCormack
Lymphangioleiomyomatosis (LAM) is a rare, low-grade, metastasizing neoplasm that arises from an unknown source, spreads via the lymphatics, and targets the lungs. All pulmonary structures become infiltrated with benign-appearing spindle and epithelioid cells (LAM cells) that express smooth-muscle and melanocyte-lineage markers, harbor mTOR-activating mutations in tuberous sclerosis complex (TSC) genes, and recruit abundant stromal cells. Elaboration of lymphangiogenic growth factors and matrix remodeling enzymes by LAM cells enables their access to lymphatic channels and likely drives the cystic lung remodeling that often culminates in respiratory failure...

Optical imaging methods have been developed to measure lymphatic function in skin; however, the lymphatic system of many organs is not accessible to this technology. Since lymphatic transport of macromolecules from any organ proceeds to the blood circulation, we aimed to develop a method that can measure lymphatic function by monitoring the fluorescence in a superficial vein of an interstitially injected tracer. We selected a 40-kDa PEGylated near-infrared dye conjugate, as it showed lymphatic system-specific uptake and extended circulation in blood...
