Affymetrix Human Genome U133A Array (hgu133a)
Description
We hypothesized that the trophoblast secretes anti-angiogenic factors, which increase in late pregnancy to limit angiogenesis. Therefore, we determined the paracrine effect of primary human trophoblasts from early versus late pregnancy on the angiogenic potential of isolated feto-placental endothelial cells.

- Affymetrix Human Gene 1.0 ST Array (hugene10st)
Description
Cells are constantly exposed to stress. Most of those stresses do not necessarily cause cell death or visible damage. The present study explores the way the immune system responds to such sub lethal stressed cells.
Publication Title
Cells exposed to sublethal oxidative stress selectively attract monocytes/macrophages via scavenger receptors and MyD88-mediated signaling.

Description
The liver stages of malaria sporozoites develop in the hepatocyte cytoplasm inside a parasitophorous vacuole (PV). The circumsporozoite (CS) protein, the major surface protein of sporozoites, traverses the PV membrane and enters the cytoplasm and nucleus of hepatocytes. CS export into the cytoplasm requires the presence of pexel/VTS motifs. The transport of CS into the host nucleus is then mediated by importin (Imp) alpha3/beta1 that binds to the nuclear localization signal of CS localized in the conserved region II-plus. The NLSs of CS and of NFkB p50 share the same Imp. The entry of NFkB p50 into the nucleus is strongly inhibited in cell lines expressing CS, and in infected hepatocytes. Micro-array data from CS expressing cell line shows that 40 NFkB targets were significantly down regulated. Among them inflammation related MIP3a and PTGS transcripts were 65 and 22 fold down regulated, thus explaining the notable absence of inflammatory cells surrounding exo-erythrocytic forms (EEFs). The presence of CS in the cytoplasm of hepatocytes enhances EEF growth both in vitro and in vivo. Therefore Plasmodium blood stages and EEFs use the same strategy to secrete proteins into the cytoplasm of host cells and remodel it to the parasites advantage.

Description
Somatic hypermutation (SHM) and class switch recombination (CSR) increase the affinity and diversify the effector functions of antibodies during immune responses. Although SHM and CSR are fundamentally different, their independent roles in regulating B cell fate have been difficult to uncouple because a single enzyme, activation-induced cytidine deaminase (encoded by Aicda), initiates both reactions. Here, we used a combination of Aicda and antibody mutant alleles that separate the effects of CSR and SHM on polyclonal immune responses. We found that class-switching to IgG1 biased the fate choice made by B cells, favoring the plasma cell over memory cell fate without significantly affecting clonal expansion in the germinal center (GC). In contrast, SHM reduced the longevity of memory B cells by creating polyreactive specificities that were selected against over time. Our data define the independent contributions of SHM and CSR to the generation and persistence of memory in the antibody system. Overall design: IgG1 and IgM light zone (LZ) and dark zone (DZ) germinal center (GC) B cells were compared in immunized AIDcre/- IgH-96K/+ R26-LSL-YFP mice.
