Strange bodies : a novel
A dizzying novel of deception and metempsychosis by the author of the National Book Award finalist Far North Whatever this is, it started when Nicholas Slopen came back from the dead. In a locked ward of a notorious psychiatric hospital sits a man who insists that he is Dr. Nicholas Slopen, failed husband and impoverished Samuel Johnson scholar. Slopen has been dead for months. Yet nothing can make this man change his story. What begins as a tale of apparent forgery, involving unseen letters by the great Dr. Johnson, grows to encompass a conspiracy between a Silicon Valley mogul and his Russian allies to exploit the darkest secret of Soviet technology: the Malevin Procedure. With echoes of both Jorge Luis Borges and Philip K. Dick, Marcel Theroux's Strange Bodies takes the reader on a dizzying speculative journey that poses questions about identity, authenticity, and what it means to be truly human.

B and T Cells Driving Multiple Sclerosis: Identity, Mechanisms and Potential Triggers
Historically, multiple sclerosis (MS) has been viewed as being primarily driven by T cells. However, the effective use of anti-CD20 treatment now also reveals an important role for B cells in MS patients. The results from this treatment put forward T-cell activation rather than antibody production by B cells as a driving force behind MS. The main question of how their interaction provokes both B and T cells to infiltrate the CNS and cause local pathology remains to be answered. In this review, we highlight key pathogenic events involving B and T cells that most likely contribute to the pathogenesis of MS. These include (1) peripheral escape of B cells from T cell-mediated control, (2) interaction of pathogenic B and T cells in secondary lymph nodes, and (3) reactivation of B and T cells accumulating in the CNS. We will focus on the functional programs of CNS-infiltrating lymphocyte subsets in MS patients and discuss how these are defined by mechanisms such as antigen presentation, co-stimulation and cytokine production in the periphery. Furthermore, the potential impact of genetic variants and viral triggers on candidate subsets will be debated in the context of MS.

Bodies of summer
\"The existence of an afterlife is now a fact: heaven is the Internet. Death is only an interruption as souls can be uploaded to the Web and new bodies can be purchased by those wishing to reenter the physical world. The need to settle an old score pushes Ramiro Olivaires to move from the comfort of virtual existence back into a human body. Ramiro's grandson, however, can only afford the body of an overweight middle-aged woman. In the shell of this new body, Ramiro must adjust to the dizzying transformations that the world has undergone since his death. Using Ramiro himself as an avatar, Castagnet walks us through a stifling new version of reality where sex, gender, identity, religion, and politics are defined by the limitless possibilities of the human body. Castagnet is considered one of the most promising new voices in Latin American literature and Bodies of Summer shows us why\" -- Provided by publisher.

Decreased Astrocytic CCL2 Accounts for BAF-312 Effect on PBMCs Transendothelial Migration Through a Blood Brain Barrier in Vitro Model
Disruption of the blood brain barrier (BBB) is a common event in several neurological diseases and in particular, in multiple sclerosis (MS), it contributes to the infiltration of the central nervous system by peripheral inflammatory cells. Sphingosine-1-phosphate (S1P) is a bioactive molecule with pleiotropic effects. Agonists of S1P receptors such as fingolimod and siponimod (BAF-312) are in clinical practice for MS and have been shown to preserve BBB function in inflammatory conditions. Using an in vitro BBB model of endothelial-astrocytes co-culture exposed to an inflammatory insult (tumor necrosis factor-α and interferon-γ; T&I), we show that BAF-312 reduced the migration of peripheral blood mononuclear cells (PBMCs) through the endothelial layer, only in the presence of astrocytes. This effect was accompanied by decreased expression of the adhesion molecule ICAM-1. BAF-312 also reduced the activation of astrocytes, by controlling NF-kB and NLRP3 induction and preventing the increase of proinflammatory cytokine and chemokines. Reduction of CCL2 by BAF-312 may be responsible for the observed effects and, accordingly, addition of exogenous CCL2 was able to counteract BAF-312 effects and rescued T&I responses on PBMC migration, ICAM-1 expression and astrocyte activation. The present results further point out BAF-312 effects on BBB properties, suggesting also the key role of astrocytes in mediating drug effects on endothelial function.

Three-dimensional microfluidic model for tumor cell intravasation and endothelial barrier function
Entry of tumor cells into the blood stream is a critical step in cancer metastasis. Although significant progress has been made in visualizing tumor cell motility in vivo, the underlying mechanism of cancer cell intravasation remains largely unknown. We developed a microfluidic-based assay to recreate the tumor-vascular interface in three-dimensions, allowing for high resolution, real-time imaging, and precise quantification of endothelial barrier function. Studies are aimed at testing the hypothesis that carcinoma cell intravasation is regulated by biochemical factors from the interacting cells and cellular interactions with macrophages. We developed a method to measure spatially resolved endothelial permeability and show that signaling with macrophages via secretion of tumor necrosis factor alpha results in endothelial barrier impairment. Under these conditions intravasation rates were increased as validated with live imaging. To further investigate tumor-endothelial (TC-EC) signaling, we used highly invasive fibrosarcoma cells and quantified tumor cell migration dynamics and TC-EC interactions under control and perturbed (with tumor necrosis factor alpha) barrier conditions. We found that endothelial barrier impairment was associated with a higher number and faster dynamics of TC-EC interactions, in agreement with our carcinoma intravasation results. Taken together our results provide evidence that the endothelium poses a barrier to tumor cell intravasation that can be regulated by factors present in the tumor microenvironment.

Sleep, death, and rebirth : mystical practices of Lurianic Kabbalah
\"In the sixteenth century, the famous kabbalist Isaac Luria transmitted a secret trove of highly complex mystical practices to a select groups of students. These meditations were designed to capitalize on sleep and death states in order to effectively split one's soul into multiple parts, and which, when properly performed, permitted the adept to free oneself from the cycle of rebirth. Through an in-depth analysis of these contemplative practices within the broader context of Lurianic literature, Zvi Ish-Shalom guides us on a penetrating scholarly journey into a realm of mystical teachings and practices never before available in English, illuminating a radically monistic vision of reality at the heart of Kabbalistic metaphysics and practice\"-- Provided by publisher.

Quantification of Malignant Breast Cancer Cell MDA-MB-231 Transmigration Across Brain and Lung Microvascular Endothelium
Tumor cell extravasation through the endothelial barrier forming the microvessel wall is a crucial step during tumor metastasis. However, where, how and how fast tumor cells transmigrate through endothelial barriers remain unclear. Using an
in vitro
transwell model, we performed a transmigration assay of malignant breast tumor cells (MDA-MB-231) through brain and lung microvascular endothelial monolayers under control and pathological conditions. The locations and rates of tumor cell transmigration as well as the changes in the structural components (integrity) of endothelial monolayers were quantified by confocal microscopy. Endothelial monolayer permeability to albumin
P
albumin
was also quantified under the same conditions. We found that about 98% of transmigration occurred at the joints of endothelial cells instead of cell bodies; tumor cell adhesion and transmigration degraded endothelial surface glycocalyx and disrupted endothelial junction proteins, consequently increased
P
albumin
; more tumor cells adhered to and transmigrated through the endothelial monolayer with higher
P
albumin
;
P
albumin
and tumor transmigration were increased by vascular endothelial growth factor, a representative of cytokines, and lipopolysaccharides, a typical systemic inflammatory factor, but reduced by adenosine 3′,5′-cyclic monophosphate. These results suggest that reinforcing endothelial structural integrity is an effective approach for inhibiting tumor extravasation.

CXCL12-mediated monocyte transmigration into brain perivascular space leads to neuroinflammation and memory deficit in neuropathic pain
Emerging clinical and experimental evidence demonstrates that neuroinflammation plays an important role in cognitive impairment associated with neuropathic pain. However, how peripheral nerve challenge induces remote inflammation in the brain remains largely unknown.
The circulating leukocytes and plasma C-X-C motif chemokine 12 (CXCL12) and brain perivascular macrophages (PVMs) were analyzed by flow cytometry, Western blotting, ELISA, and immunostaining in spared nerve injury (SNI) mice. The memory function was evaluated with a novel object recognition test (NORT) in mice and with Montreal Cognitive Assessment (MoCA) in chronic pain patients.
The classical monocytes and CXCL12 in the blood, PVMs in the perivascular space, and gliosis in the brain, particularly in the hippocampus, were persistently increased following SNI in mice. Using the transgenic CCR2
and CX3CR1
mice, we discovered that at least some of the PVMs were recruited from circulating monocytes. The SNI-induced increase in hippocampal PVMs, gliosis, and memory decline were substantially prevented by either depleting circulating monocytes via intravenous injection of clodronate liposomes or blockade of CXCL12-CXCR4 signaling. On the contrary, intravenous injection of CXCL12 at a pathological concentration in naïve mice mimicked SNI effects. Significantly, we found that circulating monocytes and plasma CXCL12 were elevated in chronic pain patients, and both of them were closely correlated with memory decline.
CXCL12-mediated monocyte recruitment into the perivascular space is critical for neuroinflammation and the resultant cognitive impairment in neuropathic pain.
