    ABSTRACT: The removal of excess cytoplasm from elongated spermatids by Sertoli cells is the last essential step in spermatogenesis. It must require the cell-to-cell recognition between Sertoli cell and elongating spermatid through protein-protein interaction. CEACAM2-L, an adhesion molecule of the immunoglobulin superfamily (IgSF), is present at the plasma membrane covering the excess cytoplasm of elongated spermatids, which might be involved in the cell-to-cell recognition. In this study, we investigated the interaction between CEACAM2-L and Poliovirus receptor (PVR) that is one of IgSFs expressed in Sertoli cells. Immunohistochemical analysis showed that CEACAM2-L expressed on elongated spermatids was in close contact with PVR-positive cell processes of Sertoli cells. Immunoprecipitation experiments both in vivo and in vitro demonstrated direct heterophilic interaction between CEACAM2-L and PVR. N-terminal Ig domain of CEACAM2-L was critical for the interaction with PVR. In addition, we found that CEACAM2-L formed heterophilic trans-tetramers with PVR in transfected COS7 cells. From these data, we proposed that Sertoli cells recognize the excess cytoplasm of elongated spermatids through the PVR-CEACAM2-L interaction in mouse testis. Keywords: CEACAM2, PVR, Sertoli cells, phagocytosis, spermatids, spermatogenesis

    ABSTRACT: Reticular cells and follicular dendritic cells (FDCs) build up a framework that underlies the compartmentalization of spleens and lymph nodes. Subpopulations of reticular cells express the smooth-muscle isoform of actin, indicative of a specialized contractile apparatus. We have investigated the distribution of the actin-binding protein caldesmon in spleen and lymph nodes of mice and rats. Caldesmon modulates contraction and regulates cell motility. Alternative splicing of transcripts from a single gene results in high-molecular-mass isoforms (h-caldesmon) that are predominately expressed by smooth-muscle cells (SMCs), and low-molecular-mass isoforms (l-caldesmon) that are thought to be widely distributed in non-muscle tissues, but the distribution of caldesmon in spleen and lymph nodes has not been reported. We have performed Western blot analysis and immunohistochemistry using four different antibodies against caldesmon, among these a newly developed polyclonal antibody directed against recombinant mouse caldesmon. Western blot analysis showed the preponderance of l-caldesmon in spleen and lymph nodes. Our results from immunohistochemistry demonstrate caldesmon in SMCs, as expected, but also in reticular cells and FDCs, and suggest that the isoform highly expressed by reticular cells is l-caldesmon. In spleen of SCID mice, caldesmon was expressed by reticular cells in the absence of lymphocytes. (J Histochem Cytochem 58:183-193, 2010).

    ABSTRACT: The pituitary gland dynamically changes its hormone output under various pathophysiological conditions. One of the pathways implicated in the regulatory mechanism of this gland is a dopaminergic system that operates the phosphoinositide (PI) cycle to transmit downstream signal through second messengers. We have previously shown that diacylglycerol kinase β (DGKβ) is coexpressed with dopamine D1 and D2 receptors in medium spiny neurons of the striatum, suggesting a plausible implication of DGKβ in dopaminergic transmission. However, it remains elusive whether DGKβ is involved in the dopaminergic system in the pituitary gland. The aim of this study is to investigate the expression and localization of DGK in the pituitary gland, together with the molecular components involved in the PI signaling cascade, including dopamine receptors, phospholipase C (PLC), and a major downstream molecule, protein kinase C (PKC). Here we show that DGKβ and the dopamine D2 receptor are coexpressed in the intermediate lobe and localize to the plasma membrane side by side. In addition, we reveal that PLCβ4 and PKCα are the subtypes expressed in the intermediate lobe among those families. These findings will substantiate and further extend our understanding of the molecular-anatomical pathway of PI signaling and the functional roles of DGK in the pituitary intermediate lobe.

    ABSTRACT: We have optimized an immunohistochemical double-staining method combining immunohistochemical lymphocyte lineage marker detection and apoptosis detection with terminal deoxyribonucleotidyl transferase-mediated dUTP nick end labeling. The method was used to trace Fas-mediated apoptosis in human reactive lymph nodes according to cell lineage and anatomical location. In addition to Fas, we also studied the expression of Fas ligand (FasL), CD3, CD20, CD19, CD23, and CD68 of apoptotic cells. The presence of simultaneous Fas and FasL positivity indicated involvement of activation-induced death in the induction of paracortical apoptosis. FasL expression in the high endothelial venules might be an inductor of apoptosis of Fas-positive lymphoid cells. In addition to B-lymphocyte apoptosis in the germinal centers, there was often a high apoptosis rate of CD23-expressing follicular dendritic cells. In summary, our double-staining method provides valuable new information about the occurrence and mechanisms of apoptosis of different immune cell types in the lymph node compartments. Among other things, we present support for the importance of Fas/FasL-mediated apoptosis in lymph node homeostasis. (J Histochem Cytochem 58:131-140, 2010).

    ABSTRACT: Identifying and scoring cancer markers plays a key role in oncology, helping to characterize the tumor and predict the clinical course of the disease. The current method for scoring immunohistochemistry (IHC) slides is labor intensive and has inherent issues of quantitation. Although multiple attempts have been made to automate IHC scoring in the past decade, a major limitation in these efforts has been the setting of the threshold for positive staining. In this report, we propose the use of an averaged threshold measure (ATM) score that allows for automatic threshold setting. The ATM is a single multiplicative measure that includes both the proportion and intensity scores. It can be readily automated to allow for large-scale processing, and it is applicable in situations in which individual cells are hard to distinguish. The ATM scoring method was validated by applying it to simulated images, to a sequence of images from the same tumor, and to tumors from different patient biopsies that showed a broad range of staining patterns. Comparison between the ATM score and manual scoring by an expert pathologist showed that both methods resulted in essentially identical scores when applied to these patient biopsies.

    ABSTRACT: Nine commercially available vascular endothelial growth factor (VEGF) antibodies were investigated for their ability to immunostain vascular malformations (VMs) with or without immature capillary proliferation. First, all antibodies were optimized for their performance in IHC, with placenta and colon adenocarcinoma as positive control tissues. Five antibodies were regarded as unfit for VEGF immunostaining based on poor immunostaining criteria. Subsequently, Western blot analysis using VEGF rabbit polyclonal antibody (Thermo RB-9031) revealed a clear 45-kDa band in tissue extracts from VMs with immature capillary proliferation and a high Ki67-labeling index, whereas tissue extracts from mature VMs without microvascular proliferation and no Ki67-labeling index demonstrated only a very weak 45-kDa band. In contrast, two VEGF antibodies, including the popular Santa Cruz A-20, revealed bands at 45 kDa of similar intensity in tissue extracts from both types of VMs. Staining characteristics of the 45-kDa band were reflected in the results obtained in IHC.

    ABSTRACT: Immunogold cytochemistry was applied to reveal the intracellular location of AMP-activated protein kinase (AMPK) subunits in liver tissue of normal rats fed ad libitum. AMPK alpha and beta subunits were located both in the cytosol and in close association with rosettes of glycogen particles (alpha particles). To reveal their true in situ association with glycogen, particular tissue processing conditions that retain glycogen in the cells were required. These included fixation with a combination of glutaraldehyde and paraformaldehyde, followed by postfixation with osmium tetroxide and lead citrate and embedding in Epon. Processing by less-stringent fixation conditions and embedding in Lowicryl led to the extraction of the glycogen deposits, which in turn resulted in the absence of any labeling. This indicates that the loss of glycogen deposits leads to the loss of closely associated proteins. Labeling for the alpha(1) and alpha(2) subunits of AMPK was found to be about 2-fold greater over glycogen than over cytosol, whereas labeling for beta(1) was 8-fold higher over the glycogen particles than over the cytosol. Immunogold combined with morphometric analysis demonstrated that the beta(1) subunits are located at the periphery of the glycogen rosettes, consistent with a recent hypothesis developed via biochemical approaches.
