Summary: The study introduces an objective method for distinguishing between chemotactic approach and blind migration based on the analysis of time-lapse recorded cell migration trajectories. The method was validated with simulated data and successfully applied to detect long-range interactions in collective systems of self-driven agents in experiments.

Summary: Learning induces the formation of new dendritic spines, which bind new presynaptic inputs into preexisting clusters, generating locally coherent inputs representing learned behaviors. Successful connections are selected based on co-activity with nearby task-related spines, ensuring the functional clustering of new spines. Furthermore, a majority of new spines synapse with previously unrepresented axons, suggesting the binding of new information into functional synaptic clusters.

Summary: Dendritic cells are antigen-presenting cells that interact with T cells to regulate adaptive immune responses. Under certain conditions, dendritic cells can develop into anti-inflammatory cells, inducing immunologic tolerance. Studies have shown that regulatory dendritic cells induce T cell tolerance by suppressing effector T cells and inducing regulatory T cells.

Summary: This study reveals the increased proportion of CD16(+) CD56hi NK cell subset and CD64(+) conventional dendritic cells (cDC2) in pSS patients, suggesting their involvement in the progression of the disease. The cDC2 can activate NK cells ex vivo and are found in proximity to NK cells in the salivary glands. The expression of NKG2D ligands on cDC2 from pSS patients is regulated by the IFN signatures associated with the RIG-I/DDX60 pathway. Injection of poly I:C leads to increased proportions of CD64hi RAE-1(+) cDC2 and NKG2D(+) CD11b(+) CD27(+) NK cells in the salivary glands.

Summary: Every type of cancer tissue is more susceptible to viral infection, which has been utilized as a new anti-cancer therapy using oncolytic viruses (OVs). OVs selectively infect and destroy cancer cells while causing no harm to the host. Research focuses on the interaction between OVs and the host immune system, particularly the role of dendritic cells (DCs) and natural killer (NK) cells in the therapeutic response.

Summary: In the neocortex, somatostatin-positive interneurons called Martinotti cells (MCs) inhibit pyramidal neurons (PNs) directly and also connect with other interneurons. These connections contribute to cortical network balance and play important roles in cognitive functions. This study found that MCs primarily connect with PNs, but also connect with other interneurons. Interestingly, the synapses between MCs and different targets exhibited specific short-term plasticity and used different GABAAR subunits. These findings provide new insights into the connectivity and molecular mechanisms of MCs in the cortical circuits.

Summary: Early life is a vulnerable period for infectious diseases and allergy development. This study compares the abundance and function of different subpopulations of innate lymphocytes in cord blood and adult blood. The results show that NKT cells and mucosal-associated invariant T cells are less abundant in cord blood, while natural killer cells and other subsets of innate lymphocytes are similarly abundant. However, the functionality of NKT cells in cord blood, such as cytokine production and expression of granzyme B, is lower compared to adults. In contrast, cord blood natural killer cells and innate lymphoid cells are abundant and capable of producing their hallmark cytokines. These findings have important implications for early life immunity.

Summary: In this paper, a nonlinear advection-diffusion model is proposed to study the interaction between immune system cells and HPV-infected cells. The model considers both the innate and adaptive immune response. A numerical explicit scheme is presented to approximate the proposed model. Numerical simulations show the temporal evolution of the model cells and identify conditions for eliminating the infection.

Summary: Microglia play a crucial role in the development of inhibitory networks, especially in the proper development of SST+ cell synapses. The molecules CX3CL1 and CXCL12 have opposing effects on the elaboration of SST+ cell axons. In terms of cortical activity development, microglia are essential for the activation of SST+ cells.

Summary: The oncogenes encoded by EBV and KSHV manipulate cellular processes like autophagy, proliferation, and apoptosis to ensure their efficient persistence and dissemination in hosts without causing pathologies in most carriers. These mechanisms allow the viruses to strike a balance between infectivity and host immune response, preventing clearance and minimizing symptoms.

Summary: Epstein-Barr virus (EBV) infects over 95% of the adult human population, usually controlled by immune responses. Genetic variations affect cytotoxic lymphocytes' role in immune control against EBV. Humanized mice models offer insights into molecular mechanisms during EBV infection and potential vaccine development.

Summary: Herpesviruses play a key role in shaping NK cell repertoires, with CMV driving NKG2C-positive NK cell accumulation and EBV expanding NKG2A-positive NK cells. While adaptive NK cells support immunity through antibody-dependent cellular cytotoxicity, NKG2A-positive NK cells seem to target lytic EBV replicating B cells. The importance of restricting EBV replication during gamma-herpesvirus pathogenesis will be discussed, along with summarizing the impact of coinfections on EBV-driven NK cell expansion.

Summary: This review summarizes epidemiological evidence supporting EBV infection as a prerequisite for MS development, describes altered EBV-specific immune responses in MS patients, and speculates on possible pathogenic mechanisms underlying the synergy between EBV infection and the MS-associated MHC class II haplotype. Therapies targeting EBV-infected B cells are being explored in MS patients, with a need for better mechanistic understanding and innovative experimental systems to test proposed mechanisms.

Summary: Strong epidemiologic evidence supports the association between Epstein-Barr virus (EBV) infection and altered immune control to the development of multiple sclerosis (MS). The mechanisms linking the two remain largely unknown. Two main possibilities for this association are discussed. Immune responses induced during a symptomatic primary EBV infection might be amplified over time, leading to central nervous system inflammation and demyelination. Alternatively, genetic predisposition and environmental factors may result in insufficient immune control of EBV-infected B cells, leading to autoimmune T cell stimulation or CNS inflammation. Understanding EBV's contribution to MS could potentially open new treatment possibilities for this autoimmune disease.
