Immunological memory is one of the core topics of contemporary immunology. Yet there are many discussions about what this concept precisely means, which components of the immune system display it, and in which phyla it exists. Recent years have seen the multiplication of claims that immunological memory can be found in "innate" immune cells and in many phyla beyond vertebrates (including

Not all B-cells generated by clonal selection mature into antibody-producing plasma cells. A significant proportion remain in the body for many years as memory cells (Ratajczak et al, 2018). Immune memory is the source of protective immunity against future infection. In a broad sense, the term refers to the immune system’s ability to recognize and mount a successful defense against a specific pathogen. ▪ Abstract Immunological memory is a hallmark of the immune system.

Immunological memory represents an important aspect of the immune response in mammals. Immunological memory exists for both B lymphocytes (antibody producing cells) and for T cells. Memory responses by the immune system occur according to only partially understood operational principles. Immunological memory is a critical evolutionary adaptation of the immune system that mediates more rapid and effective responses to previously encountered antigens.

Immunological memory is a distinct characteristic of our immune system, and it relates to its ability to remember antigens from pathogens and mount an immunological response of greater magnitude and with faster kinetics upon reencounter of the same antigens. Specifically, cells of our adaptive immune system, such as T cells and B cells, can mount specificity for the antigen, and these adaptive cells provide memory that lasts up to several decades in the body. Immunological memory is considered to be one of the cardinal features of the adaptive immune system. Despite being a recognized phenomenon since the time of the ancient Greeks, immunologists are yet to fully appreciate the mechanisms that control memory responses in the immune system.

We analyzed multiple compartments of circulating immune memory to SARS-CoV-2 in 254 samples from 188 COVID-19 cases, including 43 samples at ≥6 months after infection. Immunoglobulin G (IgG) to the spike protein was relatively stable over 6+ months. Spike-specific memory B cells were more abundant at 6 months than at 1 month after symptom onset.

Evolution can teach us which effector arms of immunological memory are biologically relevant against which virus. Antibodies appear to be the critical protective mechanism against cytopathic viruses. The absence of this factor leads to a permanent malfunction of the memory response. Until now the role of this factor for so-called CD8+ T cells was unclear. It was only after the scientists overexpressed this factor in CD8+ T cells that the importance became clear, as they could see that the survival of these cells and thus the immunological memory improved significantly. 2000-03-29 · On immunological memory.
