Intracerebral inoculation of vaccinia virus into adult DDD mice produced intensive meningitis several days after infection. The inflammatory reaction could be quantitated by counting cells obtained from this inflammatory lesion. The local virus titer increased until day 5 and subsequently decreased rapidly with time. Concomitant with this titer decrease, numerous meningeal exudate cells appeare...

The study of microbe infections has always been a very effective approach to unveil and dissect cellular pathways. Autophagy is not an exception. Although some of the breakthrough discoveries in the field were obtained using yeast, pathogens have been and still are a great tool to discover and characterize new molecular and functional aspects of autophagy. Research on pathogens has helped to ac...

OBJECTIVE To compare the pharmacokinetics and pharmacodynamics of antithymocyte globulins (ATGs) produced by two companies in the treatment of children with aplastic anemia (AA). METHODS Six children with acquired AA were divided into two groups. The patients in each group were treated with either R-ATG or F-ATG for 5 consecutive days. Venous blood samples were collected at time points of 0 h...

Mice immunized with a glucan-killed parasite vaccine exhibited enhanced resistance to Leishmania donovani infection as evidenced by decreased hepatic parasite burdens when compared to unvaccinated controls. This resistance was not seen in mice immunized with killed parasites alone. Glucan vaccination resulted in increased resistance at day 6, but this effect was no longer present by day 20 of t...

The ordered migration of thymocytes from the cortex to the medulla is critical for the appropriate selection of the mature T cell repertoire. Most studies of thymocyte migration rely on mouse models, but we know relatively little about how human thymocytes find their appropriate anatomical niches within the thymus. Moreover, the signals that retain CD4+CD8+ double-positive (DP) thymocytes in th...

Autophagy is a major intracellular degradative pathway that is involved in various human diseases. The role of autophagy, however, is complex; although the process is generally considered to be cytoprotective, it can also contribute to cellular dysfunction and disease progression. Much progress has been made in our understanding of autophagy, aided in large part by the identification of the aut...

The development and function of lymphocytes depend upon their precise migration in response to chemoattractant cytokines, or chemokines. Two recent reports suggest that, during thymic beta-selection, the binding of the chemokine CXCL12 to the receptor CXCR4 on thymocytes provides not only directional but also developmental cues.

Autophagy-related (ATG) proteins have increasingly demonstrated functions other than cellular self-eating. In this issue, Mauthe et al. (2016. J. Cell Biol. http://dx.doi.org/10.1083/jcb.201602046) conduct an unbiased RNA interference screen of the ATG proteome to reveal numerous noncanonical roles for ATG proteins during viral infection.

We developed an approach of T-cell-replete haploidentical hematopoietic stem cell transplantation (HSCT) with low-dose anti-T-lymphocyte globulin and prospectively compared outcomes of all contemporaneous T-cell-replete HSCT performed at our center using matched sibling donors (MSDs), unrelated donors (URDs), and haploidentical related donors (HRDs). From 2008 to 2013, 90 patients underwent MSD...
