Abstract
Psoriasis is an incurable cutaneous illness characterized by the presence of well-delimited reddish plaques and silvery-white dry scales. So far, there is a limited understanding of its pathogenesis, though recent discoveries on the immunological, genetic and molecular aspects of this disease have significantly contributed to the identification of new targets and the development of novel drugs. Despite these advances, many patients are still dissatisfied, so to improve patient satisfaction, reliability, and clinical outcomes, the individualization of the treatments for this disease becomes a necessity. This review summarizes recent findings related to psoriasis pathogenesis and describes new small molecules and targets recently identified as promising for treatments. Additionally, the current status, challenges and the future directions for achieving individualized therapy for this disease and the need for more collaborative studies are discussed. The individualization of treatments for psoriasis, rather than a goal, is analyzed as a process where a dynamic integration between the needs and characteristics of the patients, the pharmacological progress, and the clinical decisions takes place.

Abstract
BACKGROUND Psoriasis is one of the most prevalent immune mediated skin diseases. Selective vascular destruction by pulsed dye laser is considered one of effective laser treatments. OBJECTIVE Evaluation of the therapeutic effect of pulsed dye laser in treatment of chronic psoriatic plaque lesions and changes in human beta defensin-2(HBD-2) expression in the psoriatic patients before and after treatment, with correlation to the clinical improvement. METHODS Twenty patients with psoriatic plaque on right side treated by laser and another plaque on left side similar in size and its severity score served as control receiving no treatment. Each patient received 3-4 sessions of pulsed dye laser 595 nm. Follow up was done for three months. RESULTS There was statistically significant difference between the two psoriatic plaques (untreated and treated; A and B; p = .004). There was significant decrease in HBD-2 expression after treatment. No recurrence was observed during follow up period. CONCLUSION The pulsed dye laser is safe, effective, and tolerable treatment for resistant stable localized plaque psoriasis with minimal side effects and prolonged recurrence period.

Abstract
Insect defensins, are cationic peptides that play an important role in immunity against microbial infection. In the present study, an anionic defensin from Plutella xylostella, (designated as PxDef) was first cloned and characterized. Amino acid sequence analysis showed that the mature peptide owned characteristic six-cysteine motifs with predicted isoelectric point of 5.57, indicating an anionic defensin. Quantitative real-time polymerase chain reaction analysis showed that PxDef was significantly induced in epidermis, fat body, midgut and hemocytes after injection of heat-inactivated Bacillus thuringiensis, while such an induction was delayed by the injection of live B. thuringiensis in the 4th instar larvae of P. xylostella. Knocking down the expression of nuclear transcription factor Dorsal in P. xylostella by RNA interference significantly decreased the mRNA level of PxDef, and increased the sensitivity of P. xylostella larvae to the infection by live B. thuringiensis. The purified recombinant mature peptide (PxDef) showed higher activity against Gram-positive bacteria, with the minimum inhibition concentrations of 1.6 and 2.6 µM against B. thuringiensis and Bacillus subtilis, respectively. To our knowledge, this is the first report about an anionic PxDef, which may play an important role in the immune system of P. xylostella against B. thuringiensis.
