Macrophages comprise a highly diverse cell population expressing a continuum of biologic activities dictated by exposure to a plethora of inflammatory cues. Moreover, in contrast to most other hematopoietic populations, macrophages can arise from multiple sites-namely, the bone marrow or yolk sac, adding to the complexity of macrophage biology during health and disease. Nonetheless, it is this very type of diversity that is indispensable for macrophages to respond effectively to pathologic insults. Most of the interest in macrophage biology has been devoted to bone marrow-derived populations, but it is now becoming clearer that tissue-resident populations, which arise from distinct hematopoietic compartments, serve critical roles in host defense, including protection against neoplastic disease...

BACKGROUND: Spinal intradural arachnoid cysts (SIAC) are cerebrospinal fluid (CSF) filled sacs formed by arachnoid membranes and may be either idiopathic or acquired. Idiopathic cysts represent a separate entity and their aetiology remains uncertain. By far the most difficult differential diagnosis is distinguishing between idiopathic anterior spinal cord herniation (IASCH) and dorsal thoracic intradural arachnoid cysts (TIAC), due to their similarity in radiological appearance. Cine-mode (SSFP) is emerging as a novel technique in the diagnosis and operative planning of SIAC...

Chromosome instability (CIN) is deleterious to normal cells because of the burden of aneuploidy. However, most human solid tumors have an abnormal karyotype implying that gain and loss of chromosomes by cancer cells confers a selective advantage. CIN can be induced in the mouse by inactivating the spindle assembly checkpoint. This is lethal in the germline but we show here that adult T cells and hepatocytes can survive conditional inactivation of the Mad2l1 SAC gene and resulting CIN. This causes rapid onset of acute lymphoblastic leukemia (T-ALL) and progressive development of hepatocellular carcinoma (HCC), both lethal diseases...

Nelson Sabino Bittencourt Júnior
Late-acting self-incompatibility (LSI) has been defined as a genetically controlled self-sterility mechanism that prevents seed set by selfing, despite normal pollen tube growth and ovule penetration in self-pollinated pistils. In species of the Bignoniaceae with LSI, such as Handroanthus impetiginosus, the selfed pistils are characterized by a marked delay in ovule penetration, fertilization, and endosperm initiation, followed by uniform pistil abscission. This highlights the contentious possibility of a post-zygotic self-incompatibility system...

REVIEW
Carole Sousa, Knut Biber, Alessandro Michelucci
Microglia are essential for the development and function of the adult brain. Microglia arise from erythro-myeloid precursors in the yolk sac and populate the brain rudiment early during development. Unlike monocytes that are constantly renewed from bone marrow hematopoietic stem cells throughout life, resident microglia in the healthy brain persist during adulthood via constant self-renewal. Their ontogeny, together with the absence of turnover from the periphery and the singular environment of the central nervous system, make microglia a unique cell population...

Zhen Zhang, Zhen Liu, Zezhang Zhu, Yong Qiu
BACKGROUND: A previous study reported a high prevalence of spinal epidural lipomatosis (SEL) in patients with Scheuermann kyphosis (SK) and suggested that it may play a role in the pathogenesis of this disease. According to our observation, however, SEL occurs in other spinal kyphotic deformities as well. The aim of this study was to test the hypothesis that SEL commonly occurs in patients with different types of kyphotic deformities as a secondary intraspinal disorder. METHODS: MR images of 16 patients with congenital kyphosis (CK), 40 patients with SK, 13 patients with tuberculotic kyphosis (TK), and 69 age- and sex-matched controls were retrospectively evaluated...

Galectins are members of the lectin superfamily. They function as pattern recognition receptors in the innate immune system of vertebrates and invertebrates. A galectin homolog from the triangle sail mussel Hyriopsis cumingii (HcGal2) was cloned and characterized. HcGal2 mRNA was expressed in all tissues examined, displaying particular enrichment in mantle tissue. Interestingly, rHcGAL2 protein was only detected in the mantle, hemocytes, and gills, suggesting that post-transcriptional regulation may occur. HcGal2 expression was induced in the mantle, liver, and hemocytes after exposure to lipopolysaccharides, Gram-negative bacteria (Aeromonas hydrophila), and Gram-positive bacteria (Staphylococcus aureus)...

Immunoglobulin Y (IgY) is central to our understanding of immunoglobulin evolution. It has links to antibodies from the ancestral IgM to the mucosal IgX and IgA, as well as to mammalian serum IgG and IgE. IgY is found in amphibians, birds and reptiles, and as their most abundant serum antibody, is orthologous to mammalian IgG. However, IgY has the same domain architecture as IgM and IgE, lacking a hinge region and comprising four heavy-chain constant domains. The relationship between IgY and the mucosal antibodies IgX and IgA is discussed herein, in particular the question of how IgA could have contributed to the emergence of IgY...

BACKGROUND AND PURPOSE: Chromosomal instability is not only a hallmark of cancer, but also an attractive therapeutic target. A diverse set of mitotic kinases maintains chromosomal stability. One of these is monopolar spindle 1 (Mps1), which is essential for chromosome alignment and for the spindle assembly checkpoint (SAC). Pharmacological inhibition of Mps1 has been suggested as a cancer therapeutic; however, despite the existence of a novel Mps1 inhibitor, TC Mps1 12, no such studies have been performed...
