Development of A Novel Gene Expression System for Secretory Production of Heterologous Proteins via the General Secretory (Sec) Pathway in Corynebacterium glutamicum

Background: Corynebacterium glutamicum (C. glutamicum) is a potential host for the secretory production of the heterologous proteins. However, to this date few secretion-type gene expression systems in C. glutamicum have been developed, which limit applications of C. glutamicum in a secretory production of the heterologous proteins.Objectives: In this stu...

Excito-repellency effect of deltamethrin on triatomines under laboratory conditions.

This work demonstrates that deltamethrin in low doses produces an excito-repellency effect on triatomines, as already observed for mosquitoes. A wooden box covered with a cloth impregnated with deltamethrin at doses of 2.5 and 5mg ai/m2 was utilized for the experiment. The triatomine species studied were Triatoma infestans, Panstrongylus megistus, Rhodnius neglectus and Triatoma sordida. Adults...

Secretory immune system of rabbit ocular adnexa

tial, as seen from an initial rapid rise of each slow PHI in Fig. 3, but the contamination is again small enough for the present purpose. The three sets of tracings in Fig. 3, B, show the result of simulation with the use of the circuit in Fig. 1, B, with three different values of time constant (4.5, 9, and 18 sec) and each rod potential in Fig. 3, A, used as an input. The tracings show that th...

Secretory immune system of rabbit ocular adnexa.

A distinct system of immunity in a variety of animals is located subjacent to epithelial surfaces and is typified by the predominance of immunoglobulin A (IgA) and secretory component (SC) in various external secretions, including tears. The present study examined normal rabbit lacrimal gland, conjunctiva, and cornea for the presence of immunoglobulin and SC. IgA-staining plasma cells predomina...
