Varicella-zoster virus (VZV) directs the synthesis of a nonglycosylated polypeptide complex with two prominent species with relative molecular masses of 32,000 and 36,000; the p32/p36 complex is present in both the viral nucleocapsid and the nuclear matrix of the infected cell.

|
Antibodies to VZV p32/p36 were detected in sera from patients with both primary VZV infection (chickenpox) and VZV reactivation (zoster); the response after zoster was more pronounced.

The course of the infection was monitored by measuring lesion development, parasite load and immunological parameters (IFN-gamma and IL-10 secretion by in vitro-stimulated lymphocytes, and specific IgG isotypes), before and after challenge.

The combination of DNA vectors expressing IL-12 + IL-18 elicits high protective immune response against cutaneous leishmaniasis after priming with DNA-p36/LACK and the cytokines, followed by a booster with a vaccinia virus recombinant expressing p36/LACK.

|
To further improve this protocol of immunization, here we investigated whether the cytokines interleukin-12 (IL-12) and IL-18 could enhance protection against L. major infection in BALB/c mice.
|
9 |
12650765
|
We found that priming with DNA vectors expressing p36/LACK and either IL-12 or IL-18, followed by a booster with a VV recombinant expressing the same L. infantum LACK antigen, elicit a higher cellular immune response than by using the same protocol in the absence of the cytokines.
|

The cytokine IL-12 triggered a higher number of IFN-gamma-secreting cells specific for p36 protein than IL-18.

We have constructed a plasma protein panel of eight increased or induced proteins (p9.5, p10.5, p24a, p24b, p24c, p25a, p36 and p37), one decreased (p16) and two that are unaltered (p28a, p28b) in rainbow trout following inflammation or injection with LPS/FIA.
|

Proteins from this panel that were similar to previously identified proteins were pre-cerebellin-like (p24a), transferrin (p37) and apolipoprotein (p10.5, p24c and p28).

Recently, two members of the 6-Cys domain protein family, P52 and P36, were each shown to play an important albeit nonessential role in Plasmodium berghei sporozoite infectivity for the rodent host.
|
29 |
17517871
|
Here, we generated p52/p36-deficient Plasmodium yoelii parasites by the simultaneous deletion of both genes using a single genetic manipulation. p52/p36-deficient parasites exhibited normal progression through the life cycle during blood-stage infection, transmission to mosquitoes, mosquito-stage development, and sporozoite infection of the salivary glands. p52/p36-deficient sporozoites also showed normal motility and cell traversal activity.
|

|
However, immunofluorescence analysis and electron microscopic observations revealed that p52/p36-deficient parasites did not form a PV within hepatocytes in vitro and in vivo.

|
We demonstrated that tyrosine 23 phosphorylation resulting in surface expression of ANXA2 is required for TGFβ-induced, Rho-mediated epithelial-mesenchymal transition (EMT), linking the cellular function of ANXA2 which was previously shown to be associated with small GTPase-regulated cytoskeletal rearrangements, to the EMT process in PDA.
|

We also provide evidence that P. falciparum sporozoites of the leading vaccine candidate that is similarly attenuated through the deletion of the genes encoding the proteins P52 and P36, can develop into replicating liver stages.

Members such as P52 and P36 seem to play a role in invasion of hepatocytes, and Pfs230 and Pfs48/45 are involved in fertilization in the sexual stages and have been consistently studied as targets of transmission-blocking vaccines for years.

Among the sequences detected which ranged in size between 180 and 850 bp, genes encoding RpL41, NKTR, Rbbp4 and ANXA2 were enriched and considered possible proteins involved in tumor growth inhibition.

We previously generated a genetically attenuated parasite (GAP) by deleting the P52 and P36 genes in the NF54 wild-type (WT) strain of Plasmodium falciparum (Pf p52(-)/p36(-) GAP).
|
70 |
24827907
|
Preclinical assessment of p52(-)/p36(-) GAP in a humanized mouse model indicated an early and severe liver stage growth defect.
|
71 |
24827907
|
However, human exposure to >200 Pf p52(-)/p36(-) GAP-infected mosquito bites in a safety trial resulted in peripheral parasitemia in one of six volunteers, revealing that this GAP was incompletely attenuated.
|
72 |
24827907
|
We have now created a triple gene deleted GAP by additionally removing the SAP1 gene (Pf p52(-)/p36(-)/sap1(-) GAP) and employed flippase (FLP)/flippase recognition target (FRT) recombination for drug selectable marker cassette removal.
|
73 |
24827907
|
Using an improved humanized mouse model transplanted with human hepatocytes and human red blood cells, we show that despite a high-dose sporozoite challenge, Pf p52(-)/p36(-)/sap1(-) GAP did not transition to blood stage infection and appeared to be completely attenuated.
|
74 |
24827907
|
Thus, clinical testing of Pf p52(-)/p36(-)/sap1(-) GAP assessing safety, immunogenicity, and efficacy against sporozoite challenge is warranted.
