Single‐cell insights into the role of T cells in B‐cell malignancies
FEBS Letters, EarlyView.Single‐cell technologies have transformed our understanding of T cell–tumor cell interactions in B‐cell malignancies, revealing new T‐cell subsets, functional states, and immune evasion mechanisms. This Review synthesizes these findings, highlighting the roles of T cells in pathogenesis, progression, and therapy response, and underscoring their ...

Positive solutions for multipoint boundary-value problem with parameters
Electronic Journal of Differential Equations, 2008 In this paper, we study a generalized Sturm-Liouville boundary-value problems with two positive parameters. By constructing a completely continuous operator and combining fixed point index theorem and some properties of the eigenvalues of linear ...

FEBS Letters, EarlyView.In the adult T‐cell leukemia/lymphoma (ATL) cell line ED, the human T‐cell leukemia virus type 1 (HTLV‐1) provirus was integrated into the intron of the ift81 gene in the antisense orientation. Despite this integration, both the intact ift81 and the viral oncogene hbz were simultaneously expressed, likely due to the functional insufficiency of viral ...

Positive solutions of a boundary value problem with integral boundary conditions
Electronic Journal of Differential Equations, 2011 We consider boundary-value problems studied in a recent paper. We show that some existing theory developed by Webb and Infante applies to this problem and we use the known theory to show how to find improved estimates on parameters $mu^*, lambda ...

Positive solutions for fractional differential equation with a p-Laplacian operator
Journal of Hebei University of Science and Technology, 2015 This paper studies the following Caputo fractional differential equation with p-Laplacian of higher-order multi-point: Dβ0+(p(Dα0+u(t)))+f(t,u(t))=0,0≤t≤1,l-1<β≤l,n-1<α≤n,(p(Dα0+u(0)))(i)=0,i=0,1,2,…,l-1,u(i)(0)=0,i=1,2,…,n-1,u(1)=∑ m-

Positive solutions to sublinear elliptic problems
Colloquium Mathematicum, 2019 Let $L$ be a second order elliptic operator $L$ with smooth coefficients defined on a domain $ $ in $\mathbb{R}^d $, $d\geq3$, such that $L1\leq 0$. We study existence and properties of continuous solutions to the following problem \begin{equation}\label{00} Lu= (\cdot,u),% & \hbox{in $ $; in the sens of distribution;} \\ \end{equation} in $ ,$

Nonexistence of positive solution for an integral equation on a Half-Space R+n
, 2011 Let $n, m$ be a positive integer and let $R_+^n$ be the $n$-dimensional upper half Euclidean space. In this paper, we study the following integral equation \begin{eqnarray} u(x)=\int_{R_+^n}G(x,y)u^pdy, \end{eqnarray} where \begin{eqnarray*} G(x ...

Rewriting the dendritic cell code in cancer—from subset identity to immunotherapeutic design
FEBS Letters, EarlyView.Dendritic cells (DCs) play central roles in cancer immunity but are often subverted by the tumor microenvironment. This review explores the diversity of DC subsets, their functional plasticity, and emerging therapeutic strategies to reprogram DCs for enhanced antitumor responses, including vaccines, in vivo targeting, and DC‐based immunotherapies ...
