Abstract

Infeksi primer terjadi bila virion HIV dalam darah, semen, atau cairan tubuh lainnya dari seseorang masuk ke dalam sel orang lain melalui fusi yang diperantarai oleh reseptor gp120 atau gp41. Tergantung dari tempat masuknya virus, sel T CD4+ dan monosit di darah, atau sel T CD4+ dan makrofag di jaringan mukosa merupakan sel yang pertama terkena. Sel dendrit di epitel tempat masuknya virus akan menangkap virus kemudian bermigrasi ke kelenjar getah bening. Sel dendrit mengekspresikan protein yang berperan dalam pengikatan envelope HIV, sehingga sel dendrit berperan besar dalam penyebaran HIV ke jaringan limfoid. Di jaringan limfoid, sel dendrit dapat menularkan HIV ke sel T CD4+ melalui kontak langsung antar sel.

Abstract

A consistent kernel-type nonparametric estimator of the intensity function of a cyclic Poisson process in the presence of linear trend is constructed and investigated. It is assumed that only a single realization of the Poisson process is observed in a bounded window. We prove that the proposed estimator is consistent when the size of the window in definitely expands.DOI : http://dx.doi.org/10.22342/jims.15.1.42.37-48
