1. Cellular structures, cellular/dendritic transition and dendritic structures during transient unidirectional solidification / Estruturas celulares, transição celular/dendritica e estruturas dendriticas na solidificação unidirecional transitoria
As morfologias das estruturas de solidificação, caracterizadas principalmente por arranjos celulares e dendríticos, e suas grandezas representadas por espaçamentos celulares e dendríticos primários, secundários e terciários, controlam os perfis de segregação e a formação de segundas fases dentro das regiões intercelulares ou interdendríticas, q

2. COX-2, a synaptically induced enzyme, is expressed by excitatory neurons at postsynaptic sites in rat cerebral cortex.
Postnatal development and adult function of the central nervous system are dependent on the capacity of neurons to effect long-term changes of specific properties in response to neural activity. This neuronal response has been demonstrated to be tightly correlated with the expression of a set of regulatory genes which include transcription factors as well as

3. Sorting and directed transport of membrane proteins during development of hippocampal neurons in culture
Hippocampal neurons in culture develop morphological polarity in a sequential pattern; axons form before dendrites. Molecular differences, particularly those of membrane proteins, underlie the functional polarity of these domains, yet little is known about the temporal relationship between membrane protein polarization and morphological polarization. We took

4. Peyer’s patch organogenesis is intact yet formation of B lymphocyte follicles is defective in peripheral lymphoid organs of mice deficient for tumor necrosis factor and its 55-kDa receptor
Targeted inactivation of genes in the tumor necrosis factor (TNF)/lymphotoxin (LT) ligand and receptor system has recently revealed essential roles for these molecules in lymphoid tissue development and organization. Lymphotoxin-αβ (LTαβ)/lymphotoxin-β receptor (LTβ-R) signaling is critical for the organogenesis of lymph nodes and Peyer’s patches and

5. Vascular cell adhesion molecule 1 and alpha 4 and beta 1 integrins in lymphocyte aggregates in Sjögren's syndrome and rheumatoid arthritis.
OBJECTIVES--Interactions between vascular cell adhesion molecule 1 (VCAM-1) and its ligand, the alpha 4/beta 1 integrin, have been shown to be important in a number of cellular events in vitro. To assess the importance of such interactions in the development of lymphocytic infiltration in diseased tissue the distribution of the two ligands has been studied i

6. Structural Relationships and Cellular Tropism of Staphylococcal Superantigen-Like Proteins
The staphylococcal superantigen-like proteins (SSLs) are a family of polymorphic paralogs encoded in the Staphylococcus aureus genome whose function is unknown. The crystal structure of SSL7 was determined and compared to that of SSL5 and that of a classical superantigen, streptococcal pyrogenic exotoxin. Although the overall architecture of the superantigen

7. An ultrastructural study of the ciliary ganglia of cat and monkey (Macaca fascicularis) following section of the short ciliary nerves.
The ultrastructural changes in the ciliary ganglion of the cat and monkey after postganglionic (short ciliary) nerve section are described. They were similar in both cat and monkey. The nucleus became irregular with prominent indentations on the 3rd day after operation and was peripherally located in the neuron from the 5th postoperative day; by 1 month post

8. cAMP signaling in neurons: patterns of neuronal expression and intracellular localization for a novel protein, AKAP 150, that anchors the regulatory subunit of cAMP-dependent protein kinase II beta.
In mammalian brain, physiological signals carried by cyclic AMP (cAMP) seem to be targeted to effector sites via the tethering of cAMP-dependent protein kinase II beta (PKAII beta) to intracellular structures. Recently characterized A kinase anchor proteins (AKAPs) are probable mediators of the sequestration of PKAII beta because they contain a high-affinity
